New Glow-in-the-Dark Fish Identified

With distinct tubular eyes and a natural glow, two species of bioluminescent deep-sea fish nicknamed “barreleyes” have been identified. The newly described species are part of the family Opisthoproctidae. Barreleye fish are not well-described, due to the rareness and fragility of specimens, the researchers said. These fish are “one of the most peculiar and unknown fish groups in the deep-sea pelagic realm, with only 19 morphologically disparate species,” the scientists wrote in their new study. However, the scientists were able to determine the two newfound species through comparisons of pigment patterns on the fish’s “sole.” This organ, found along the belly of some bioluminescent species, controls the light emitted from a different, internal organ. These two organs give the fish their glowing

Reef Threads Podcast #286


One of the coral beauty fish that Kathy Leahy has raised from egg to settle and adult color.

We end our one-week hiatus with a terrific discussion with marine fish breeder Kathy Leahy. In the podcast we talk about fish breeding in general, the recent MBI conference, and, most exciting, Kathy’s success as the first person to raise the coral beauty from eggs to settle. We apologize for the few moments when technology let us down, but are confident you’ll enjoy the discussion. Download the podcast here, or subscribe to our podcasts at iTunes. Also, follow us on Twitter at reefthreads.—Gary and Christine

Jellyfish Watch

With summer ending and school just beginning, Jellyfish season is in high gear. While fishing at the coast this past weekend I noted that the Jellyfish and Sea Nettle populations are well represented.  Higher water temperatures bring larger and more concentrated populations of the relatively harmless Cannonball Jellyfish and venomous Atlantic Sea Nettles, Chrysaora quinquecirrha.  There have also been reports of box jellyfish (Chiropsalmus quadrumanus) or four handed jellyfish as they are commonly called in the Myrtle Beach area.  Fortunately these jellyfish are not as common as our Cannonball Jellyfish but they can be found in the Atlantic Ocean, the Gulf of Mexico and the Pacific Ocean. The sting is venomous and dangerous to humans, especially children. Photo Credit: Jellyfish Watch http://www.jellywatch.org/node/6715

A look at Wrasses; The Labridae Family

Wrasses are one of the most common fish in the aquarium trade but did you know that there are over 600 species of identified Wrasses within 82 genera; making Wrasses one of the largest fish families.  Typically, wrasses are small in size with most maturing to under 8 inches long.  However, some such as the Humphead wrasse can grow to over 8 feet in length!   While most wrasses are efficient carnivores, typically feed on small invertebrates, the Humphead feeds on mollusks, reef fish and sea urchins. Some have even been known to eat poisonous sea hares, boxfish and crown-of-thorns starfish.

Review: Coast To Coast Custom Aquariums Frag Tank

Coast To Coast Custom Aquariums. This aquarium, a 187 gallon low iron tank with euro bracing and an external overflow, was a piece of art as the quality and craftsmanship were top notch. It was the Porsche of fish tanks! Yes, it was time to rethink my frag tank setup. For my prior setup I went with an acrylic frag tank since it was much cheaper and lighter then glass. Nonetheless, there were some tradeoffs, as the acrylic on this 44 gallon tank scratched easily and the eurobracing began to warp. I have always been an advocate of investing in quality products (you get what you pay for) since well built products are engineered to last long and are trustworthy. Yes, a frag tank is typically not on “display”
