Aquarium Corals: Stony Coral Parasites: Red and Black Bugs: Identification Guide, Preventive Measures, and a Review of Treatment Protocols

by | Mar 15, 2010 | 0 comments

This month, we’ll take a look at something most hobbyists would prefer to never see – coral parasites of genera Alteuthellopsis, Parategastes, and Tegastes (the latter two commonly called ‘red’ or ‘black bugs’).

  • Order: Harpacticoida
    • Family: Peltidiidae
      • Genus: Alteuthellopsis
    • Family: Tegastidae
    • Genus: Parategastes, Tegastes

As a general rule, ‘bugs’ of Order Harpacticoida are smaller in size than Xarifiid copepods, with a length of about 0.5mm being the maximum size. They are generally considered to be endoparasites and are thought to reside mainly in coral polyps’ gastrovascualr cavity.

Order: Harpacticoida; Family: Peltidiidae; Genus: Alteuthellopsis

Alteuthellopsis corallina

  • Hosts: Acropora exigua, Astreopora sp., Goniastrea retiformis, Merulina ampliata, Montipora verilli, Platygyra daedala, Platygyra sp., andPocillopora damicornis.
  • Maximum Reported Size (female): 0.63mm
  • Maximum Reported Size (male): 0.57mm
  • Color: Slightly opaque gray, red eye, egg sacs dark brownish gray.
  • Locality: Eniwetok Atoll, Marshall Islands, Lizard Island, GBR
  • Reference: Humes, 1981

Order: Harpacticoida; Family: Tegastidae; Genus: Parategastes, Tegastes: Common Name: Red bugs, black bugs

‘Red bugs’ are the bane of Acropora keepers and it is popular belief among hobbyists that they are the only parasites of stony corals. The ‘evil’ Tegastes acroporanus has been officially described from but one Acropora species.

Copepods of the family Tegastidae (Crustacea, Copepoda, Harpacticoida) are characterized by a laterally compressed amphipod-like body, a modified male genital area, and nauplii possess a claw-like mandible (Lang 1948, Ivanenko et al. 2008). About 60 species belonging to 6 genera have been described, although those listed as parasitic to corals are small relative to the number of Xarifiid species known to infest corals. As a rule of thumb, Tegastidae copepods are much smaller than xarifiid copepods.


Figure 134. Tegastes cnidicus. Although not a known coral parasite (this species prefers hydrozoans), its shape is representative of its kind. Lateral view.


Figure 135. Tegastes cnidicus. Dorsal view.

Except for the deep-sea species Smacigastes micheli (Ivanenko & Defaye 2004), all tegastid species have been found in shallow water habitats in association with algae, bryozoans and/or cnidarians. Not all are animal parasites. For instance, Tegastes nanus is found in association with the red alga Ceranium and brown algae genera Fucus and Laminaria. Tegastes falcatus feeds upon suctorian cilicates found on the bryozoan Flustra foliacea, while T. longimanus is found along sheltered rocky shores and salt lakes. T. acroporanus is a known parasite of at least one coral, the Pacific Acropora species A. florida.

Parasitic Copepods in the Reef Aquarium

An aquarium differs radically from a natural environment, and a quite different from a coral reef. Temperature, nutrients, and a number of other factors may contribute to unnatural populations or outbreaks of copepod populations. While these may contribute to abnormal infestations, hobbyists do have a number of methods available to them, including quarantine, chemical control or eradication, biological controls including deliberate manipulation of physical and chemical parameters, as well as selective control by natural predators.


The old adage ‘An ounce of prevention is worth a pound of cure’ applies to both quarantine and husbandry procedures. However, the effectiveness of currently accepted pre-treatment and quarantine procedures are yet to be validated for many parasitic copepod genera.

Parameters Possibly Affecting Parasite Populations

Part of a successful control strategy for parasites might include manipulation of physical parameters. We’ll briefly discuss two – temperature and water motion. These are easily (but not necessarily inexpensively) controlled.


Temperature is an easily measured parameter of any body of water and its importance in the regulation of biological and biochemical reactions is well recognized. Yet, I saw very little mention of temperature while reviewing a number of hobby-related works on parasites. However, Sparks (1985) mentions temperatures in the lower range of tolerance as important in keeping parasites, disease, etc. in check. Further, Jacoby and Greenwood (1989) reported statistically significant seasonal changes in demersal zooplankton populations in Australia (including Parategastes copepods known to preferentially inhabit certain algal beds – other Parategastes species are parasites of certain coral taxa).

Humes and Lee, 1985 found parasitic copepod Anthessius populations rose in populations of the clam Pecna in water off Hong Kong during the later part of the year. When compared to average environmental data (water and air temps, rainfall) for the area, it appears there is a general trend of more ‘bugs’ during times of warmer water. However, this time is also one of lessened rainfall that could reduce lessened nutrient loadings. This observation is by all means not conclusive, but it is an interesting one. See Figures 147 and 148.

Any seasoned hobbyist has seen blooms of various (usually undesirable) organisms within aquaria and all are due to a domino-effect of change, some undoubtedly triggered by warm water. Although we have lots of subjective evidence, work remains to be done on the effects of temperature and coral parasite populations. Maintaining the temperature as low as 22°C (~72°F) in an aquarium for tropical fishes and invertebrates should present no problems.

Water Motion

Experienced snorkelers or divers know that natural coral reefs are subjected to much higher water motion than seen in most aquaria. The high water velocity could serve to remove parasites from corals’ tissues where they are hence eaten by fishes. It is really a matter of speculation that low water movement might encourage parasitic infestations, however it is generally accepted that zooxanthellae photosynthesis is proportional (up to a point) to water velocity when sufficient light energy is available. If water motion is low, then the amount of nutrient obtained by the coral from the symbiotic Symbiodinium might also be low. In this case, the coral’s energy reserves could also be limited, thus an infestation by parasitic copepods might have more of an effect.

Isolation from the Host

During preparation of this article hundreds of Tegastes (or Parategastes) parasites were isolated from the host coral, and were examined microscopically for a number of days. Oddly, not one female with egg sacs was observed. These bugs remained isolated from the host for about 4 days before dying. However, plenty of protozoa were observed in the sample, suggesting that environmental conditions (dissolved oxygen, pH, etc.) were not the cause of copepod deaths.

Why were there no females reproducing? Are these particular parasitic copepods unusually long lived making rapid reproduction unnecessary?

Treatments for Parasitic Copepods

The very first question that should be asked is ‘Should I treat?’ The very best scenario is no parasites at all, but a few might do no significant harm. In addition, some parasitic copepods seem to have a high fidelity to specific coral species and the risk of infection of other coral species might be non-existent or minimal. However, infestations resulting in loss of corals’ color, polyp expansion, or general malaise should be taken seriously and followed with a regimented treatment protocol.

Copepods succumb to a variety of chemicals, and a review of older material (Kabata, 1970; Dulin, 1976) suggests use of insecticides such as DDT (!), lindane (!) and Dylox. Fortunately we don’t have to resort to such drastic (and dangerous) methods for control of coral parasites.

Successful treatments for copepods infestations are dependent upon many factors. The resistance of the animal against the treatment procedure is something we know very little, although there is little to suggest that one genus of copepod is more resistant than others to a certain ‘medication.’ If we consider each ‘bug’ is equally susceptible, then two other factors are involved: Dosage and Length of Treatment. These are being refined, as the information below states.

Quarantine Treatments for Red and Black Bugs

There are several products for ‘bug control’ available to hobbyists. With the exception of the ReVive product (obtained as a manufacturer’s sample), these solutions were obtained through normal retail channels. All were tested using the following protocols.

Testing Protocol

Since I do not have access to all the coral parasites, I decided to conduct some bioassays using similar creatures. Note that we should not be concerned with only the target organism, but should examine the effects of the medication on a variety of organisms. Also included are observations made by a select group of hobbyists. These comments should not be considered to be comprehensive, but as results obtained with a specific ‘bug’ species under the conditions of testing.

Protocol: Snails, planarians, and copepods were collected from a freshwater pond and divided into a study group and a control group. These groups were placed into stainless steel pans containing one liter of pond water. Medication was added per the manufacturer’s recommendations. Observations were made continuously during the recommended treatment time, after which at least one water change was made. A final observation was made after 24 hours. These trials were conducted twice, about 1 week apart.

ReVive Coral Cleaner

  • Manufacturer: Two Little Fishies
  • Contains: Oleum abietis, 5,000 mg/l; Citrus limon, 5,000 mg/l (or 0.5% each)
  • pH: 5.27 @ 24.2°C. – Does not adversely affect water pH when following manufacturer’s dosing recommendations.
  • 1 capful = 8 milliliters
  • Marked Expiration Date: No

Figure 149. ReVive, a ‘coral cleaner’ from Two Little Fishies.

This product is effective against crustaceans, including copepods. It is not intended for treatment of whole aquaria.

The label lists two main active ingredients: Oleum abietis (pine or fir oil) and Citrus Limon (lemon peel extract). Pine oil is often used by humans as a decongestant, and it has antiseptic properties. Cold-pressed extracts of lemon peels has various commercial and industrial uses.

The bottle I obtained is not marked with an expiration date. When stored properly (in the dark and refrigerated) it probably has a shelf life of a year or two. When citrus limon degrades, it develops a turpentine odor and this might used as an indicator of product condition.

I found this product to be an effective coral cleaner. A Montipora specimen was soaked in a Revive solution for 16 minutes, although copepods and other crustaceans had abandoned the coral a few minutes after the treatment began. The coral exhibited some mucus discharge (about that seem when most corals are handled) and was soaked in ReVive-free aquarium water before being returned to the aquarium. The Revive solution and debris was poured through a 190 micron mesh, and the collected material was examined with the aid of a microscope. Various amphipods and copepods, plus a number of unidentified animals were observed. See Figure 150. The kill rate of copepods was 100%.

The aforementioned Montipora specimen was chosen for treatment because it had inexplicably lost most of its vibrant orange coloration, and batteries of testing had failed to reveal any environmental (mostly chemical) clues. After about 3 weeks, I noticed that portions of the specimen were regaining its orange fluorescence. Although I cannot guarantee that the cleansing dip was responsible for the return of coloration, I am at a loss to provide an alternate explanation.


Figure 150. A copepod ‘chased’ from a Montipora specimen by the ReVive product. Note the brown dots within the crustacean – are these zooxanthellae, or simply natural coloration? Photomicrograph by the author.

Results of ReVive Treatment (Using freshwater animals, protocol described above):

  • Unidentified Crustaceans: 94% kill rate after 15 minute dip
  • Snails: Initially stunned by the treatment, but apparently fully recovered when observed at 24 hours.

MelaFix Marine

  • Manufacturer: Aquarium Pharmaceuticals
  • Contains: Oil of the Meleluca Tree, 12,500 mg/l (or 1.25%)
  • pH: 4.16 @ 22.1°C. Does not adversely affect water pH when following manufacturer’s dosing recommendations.
  • 1 capful = 11.3 milliliters
  • Marked Expiration Date: Yes. Purchased in October 2009. Expiration date is July 2012.

Figure 151. Melafix, a ‘coral remedy’ from API.

Aquarist Steve Ruddy kindly relayed his experiences with ‘black bugs’ (see Figures 5, 6, and 7) and MelaFix. He found that black bugs abandoned the host coral (a Montipora species – See Figure 4) about 20 minutes after the treatment began. Note: Ruddy’s treatment time of 20 minutes exceeds the manufacturer’s maximum recommended time of 5 minutes. These copepods settled to the bottom of the container and swam in circles, and all motion stopped 30 minutes after treatment started. However, the parasites were not killed during the treatment process, and were still alive some 24 hours after the treatment began.

We should note that Meleluca oil is considered a carcinogen by the State of California, and the bottles of Melafix Marine are so marked.

Results of Melafix Treatment (Freshwater animals used, protocol described above):

  • Unidentified Crustaceans: 97.5% kill rate after 15 minute dip*
  • Snails: Initially stunned by the treatment, but apparently fully recovered when observed at 24 hours.

*An interesting observation. When comparing the kill rates of different copepods, it is apparent that this product is very effective against some bugs, and not so against others. This point may be moot, as Ruddy found it worked very well when used to drive (but not kill) bugs from a Montipora coral during a quarantine ‘dip’.

Pro-Coral Cure

  • Manufacturer: Tropic Marin
  • Contains: Iodine, about 5,600 mg/l (or 0.56%)
  • pH: 6.49 @ 22.0°C – Does not adversely affect water pH when following manufacturer’s dosing recommendations.
  • Marked Expiration Date: No

This product’s container uses a small push-pump to dispense the iodine solution. I found it to deliver 0.7 milliliters (it is advertised to dispense 1 ml). I bring this up as I found the pump awkward and messy to use and chose to measure the solution using a suction bulb and pipette. For those dispensing the product manually, a dose smaller than recommended seems to work well (see results below).


Figure 153. Pro-Coral Cure, an iodine-based product from Tropic Marin.

Results of Pro-Coral Cure Treatment (Freshwater animals used, protocol described above):

  • Unidentified Crustaceans: 94% kill rate after 15 minute dip
  • Snails: Initially stunned by the treatment, but apparently fully recovered when observed at 24 hours.
  • This product was also tested as an agent of flatworm control. We’ll discuss this in a future article.

Product Shelf Life of ‘Coral Dips’

Dosage is based upon the reactive agent content. Most products have a limited shelf life and an expiration date is (or should be) marked on the container. For example, meleluca degrades upon exposure to light, heat, humidity and exposure to air, and the product containing it (MelaFix, Aquarium Pharmaceuticals) has an expiration date on the bottle. This date is there for a reason – don’t ignore it. Store these and other products in dark, cool dry conditions and in a container containing little air (Carson et al., 2006) to avoid considerable changes in the chemical makeup. The only indictor of spoilage of which I am aware is the potential development of a turpentine odor.

Two Little Fishies product (ReVive) has no expiration date.

The Tropic Marin Pro-Coral Cure is not marked with an expiration date. Iodine degradation is often linked to light intensity. Store this product in the dark.

Ethyl and Methyl Alcohols

Ethyl and methyl alcohols are toxic to invertebrates, depending upon the dose of course. In various papers, the copepod expert Arthur Humes mentions using 95% ethyl alcohol to make a 5% solution of alcohol and seawater. He soaked various corals in this solution over timeframes of several hours to overnight, and found endoparasitic copepods would abandon their host. I tried this, and found it true, but it also killed the coral host.

In-Tank Treatments for Red and Black Bugs

In-tank treatments fall into two general categories – biological and chemical. Personally I would prefer a natural means of controlling coral parasites, however, there are many issues surrounding this protocol. I suppose it is an overall lack of success I’ve had over the years when choosing fishes, crabs, nudibranchs and other animals for elimination of some sort of pest.

Biological controls are subject to the independent whims of parasite predators. Long-time hobbyists recognize that individuals of a given fish species have their own personalities and behaviors. For instance, some Copperband Butterflyfishes will destroy Aiptasia colonies, while another Copperband might show little or no interest in a diet of Aiptasia anemones. Other fishes may have specific dietary requirements, and elimination of parasites through predation could result in loss through starvation of the predatory fish. As we have seen, many coral parasites reside within coral tissues and successful bio-removal would involve substantial loss of coral tissues – a case where the cure for parasites is successful due to the loss of the host. However, my experiences will not necessarily be yours. I wish you the best of luck in our endeavors.

Chemical Treatments

Milbemycin Oxime (Interceptor™)

  • Manufacturer: Novartis AG
  • Treatment protocol developed by Dustin Dorton.
  • Comments: Store milbemycin oxime at room temperature.

Interceptor is a medication marketed for treatment of canine scabies, eye worms, roundworms, hookworms, whipworms, and heartworms in dogs, and it has been found to be effective against at least some parasitic copepod taxa.

According to Dorton, 1 Interceptor™ tablet (intended for large dogs weighing 51-100 pounds) weighs one gram and contains 23 milligrams of milbemycin oxime. One tablet is ground to powder and 25 milligrams is added to a small container of aquarium water and mixed (this might take quite a bit of stirring). This water containing 25 mg of the tablet is sufficient to treat 10 gallons of actual water volume in the aquarium. In other words, 1 tablet containing 23 mg of milbemycin oxime will treat 380 gallons, according to Dorton (400 gallons according to my calculation). A local school or university, laboratory, or larger water or wastewater treatment plant will have an analytical scale (or balance). They might perform weight analyses for you.*

  • Remove all shrimp and crabs from the aquarium. Remove mechanical filtration and activated carbon. Turn off UV sterilizers and protein skimmers (but water should still circulate through these vessels in order for these volumes of water to be medically treated as well).
  • Add a sufficient amount of medication to the aquarium. Allow treatment to proceed for 6 hours, and perform a 25% water change. Resume use of carbon, skimming, etc.
  • Repeat this procedure 7 days later, and again after 14 days.
  • * Dosage is apparently not as critical as suggested by Dorton, as time has confirmed that higher concentrations (5x or more than that recommended by Dorton) of milbemycin oxime does little, if any, harm to corals.

Milbemycin Oxime and Lufenuron (Sentinel™)

  • Manufacturer: Novartis AG
  • In addition to milbemycin, this product also contains lufenuron for flea control.

Lufenuron (Program™)

  • Manufacturer: Novartis AG
  • Not recommended for use as a coral treatment.

Ivermectin (Stromectol™, Ivomec™, HeartGard™, Iverhart Plus™, Tri-Heart Plus™ and Acarexx™)

Ivermectin is a treatment for lice, mites, ear mites and is also an antihelmitic (effective against roundworms, heartworms, and lungworms) in cattle and swine. It is also prescribed for humans as a treatment for Bancroft’s filariasis and scabies.

Wright (2009) suggests this treatment protocol: Dissolve Ivomec (1% solution) in propylene gycol (an alcohol). Dose at 0.75 mg/l per gallon (actual volume). Wright’s article used 34 mg in 45 gallons).

Turn off the protein skimmer, UV sterilizer, and canister filters and disperse the Ivomec solution in a strong stream of water within the aquarium. After 12 hours, filter water using fresh activated carbon and resume use of the protein skimmer and UV sterilization. Repeat this treatment every two weeks for a total of 3 times.

The author (Wright) cautions that this treatment might harm arthropods, mollusks, crustaceans, other invertebrates (I’m assuming he doesn’t mean corals other than the Acropora specimen mentioned in the article) and angelfishes.

MelaFix Marine

  • Manufacturer: Aquarium Pharmaceuticals
  • See details listed above. API recommends this product for whole-tank treatment, but these claims have not been evaluated by this writer.


Not all copepods that associate with scleractinians are harmful. However, our lack of knowledge forces us to make an assumption that corals crawling with copepods are in danger.

  • There are hundreds, perhaps thousands of coral parasites. It seems there are specialist parasites found in or on specific coral species, while others are generalists and might infest and feed on a number of coral species. Although there is some indication within the hobby that ‘bugs’ might adopt a new home coral species if their host dies, it will take years of work to establish how parasites behave in artificial environments.
  • It is not uncommon for hobbyists to mix Atlantic corals (sea whips, sea fans, Manicina, etc.) together with Pacific coral species. We understand nothing of how parasites from different locales interact with foreign potential hosts.
  • Parasitic copepods may introduce bacterial pathogens.
  • Many parasites are internal and are not readily apparent, where endoparasites living in the gastrovascualr cavities remain hidden from view. Stock (1988) discusses the ease which Pacific endoparasites are coaxed from host coral tissues. Internal parasites of Atlantic/Caribbean corals are more difficult to remove than those of their Pacific counterparts – indeed, this researcher states that parasites of the Family Corallovexia (and perhaps Corallonoxia) were apparent only after host tissues were chemically dissolved. Does this mean that current treatment protocols are incapable of purging host tissues of their copepod parasites? Without further documentation, this question must remain unanswered.
  • Some copepod parasites consume coral tissues, including symbiotic zooxanthellae, which are then incorporated into the parasites’ bodies. Presumably, the parasite forms a symbiotic relationship with Symbiodinium sp. Thus some parasites not only consume coral tissues but rob corals of the benefits of their algal symbionts. Large numbers of external parasites could also shade zooxanthellae and cause of loss of beneficial nutrient recycling.
  • The number of bugs on a coral is only part of the equation. It is the degree of trauma caused by the parasite, where the amount of damage is compared to the amount of tissue. Simply dividing corals into the categories of ‘large polyp’ and ‘small polyp’ could be insufficient in estimating potential impacts of parasites. In the case of SPS corals, the hobbyist should consider the porosity of the coral skeleton. Perforate skeletons are porous while imperforate skeletons lack these channels that often contain soft living coral tissues. For instance, Montipora and Porites corals are generally highly porous and superficial tissue damage is less likely to become a health issue. On other hand, some corals (such as Pocillopora meandrina) have non-porous, rock-hard skeletons and damage to the paper-thin layer of soft tissues simply covering the skeleton might have a far greater impact than the same amount of damage to a perforate coral. Acropora species are usually listed as possessing imperforate skeletons. However, those hobbyists with a lot of experience in fragging Acroporas have noted living tissue channels running within the skeleton. Hence, Acroporas defy a simple sorting and must be judged on a case-by-case basis. This could explain why ‘bugs’ are not much of an issue with soft corals.
  • Specific chemical treatments may not be a universal cure for coral parasites. There is evidence that a prescribed treatment will eliminate some ‘bugs’ but only irritate others.
  • Quite a few photographs exist of ectoparasites Tegastes, Parategastes, and others. Despite the large number of parasitic Xarifid copepods, no photographs of these bugs have been provided by hobbyists. This suggests endoparasites (despite being larger in size and in number of species) are not abundant in number in important aquarium coral species, or have simply been overlooked due to their hidden and/or tenacious nature. Current pre-treatment methods are encouraged, yet we do not know if they are effective against endoparasitic copepods.
  • Biological controls for some copepods are available, but these are sometimes a hit-or-miss proposition.
  • Without the presence of a host, some copepods (specifically the Tegastes(?) bug seen in Figure 7) will survive for only a few days (~48 hours, based on limited observations).
  • Hobbyists using medications for in-tank treatments should expect losses of livestock. This could be a result of sensitivity of the organism(s) to the toxic nature of the chemical, or perhaps as through secondary effects. To my knowledge, no one has investigated the responses of nitrifying bacteria to medications mentioned in this article. Nitrifying bacteria populations are generally more easily upset than their carbonaceous counterparts.

This article is but a small tool for use by serious hobbyists in answering many questions. Hobbyists are encouraged to photo-document individuals observed during parasitic outbreaks, as well as compare notes on those environmental factors possibly encouraging explosion of parasite populations.

For now, prevention of aquarium infestation has to rely to two simple procedures: Treatment to removal existing parasites followed by a quarantine period to prevent introduction of any surviving egg masses or adults. Once the corals are in the display aquarium, treatment and control of parasite infestations becomes much more complex in nature. Medications are simply a band aid for treatment of environmental factors aiding in an explosion of parasite populations and it unclear if present treatment protocols are effective against all parasitic genera. Investigations of biological controls are encouraged, but hobbyists should accept results are not guaranteed for either eradication of parasites or long-term survival of the predator.

Next time, we’ll examine copepod parasites found on soft corals, gorgonians and Tridacna clams.
