I hope everyone out there is listening. I have written about the elegance coral problem in my FAMA column Reef Notes (more than once) and have spoken about it at my various lectures. I don't know why my advice on this point has fallen on deaf ears.
The problem with elegance coral (Catalaphyllia jardinei) that has only occured the past several years is caused by bacteria.
If you first treat the coral in either Nitrofurazone or Doxycycline for about four or five days it will not suffer the shrinking and wilting/rotting then dying problem. Corals suffering the problem can be cured by treatment if it is initiated early enough.
The problem is NOT caused by starvation. Please do not continue to spread that myth as it results in the death of more coral.
Tom, you are an excellent aquarist running a great shop. Please treat the elegance corals with antibiotics in a quarantine system. Please post your results here, preferably renewing the topic every week, until a few people in the industry get a clue. Apparently I alone cannot tell enough people that when something is on fire they should try to put the fire out. This is such an easy problem to solve.
I have visited may wholesale facilities and recommended that they treat the elegance corals. No one does it though. Dealers could also easily do this to help their customers.
Another point- if you place a sick elegance coral in a tank that contains a healthy one, the disease is contageous. Both may die. It can also be passed to other corals, but usually remains confined to elegance. That is a fascinating point, worth studying.
I hope no idiot gets on this forum and accuses me of creating a false story about bacteria and elegance corals. I have no interest in stirring up controversy- my interest here is to answer the question correctly and to help improve the hobby.
I believe that it is irresponsible to receive elegance corals and not treat them with antibiotics. Their chance of survival lately without treatment is very slim. With treatment they become very hardy, as they used to be.
I cannot explain why this disease suddenly became a problem a few year back. All I know is that it did, and continues to be a problem today.
Regarding where elegance corals come from- it is true that they are lagoon dwellers, but that has no bearing on their success in aquariums with regard to nutrients. They can be found in shallow seagrass flats and on deep reef slopes (yes, on reefs). I have seen them in various habitats in Australia, the Solomon Islands, and in Japan. They do usually occur with their base in mud or sand, sometimes on coral rubble.
Sincerely,
