yellow polyp disease

[briareos]

I have a strange disease that affects yellow polyps in my tank.

basically, any yellow polyp that I put in there degenerates into a grey mass after a day. This occurs for zoanthids, as well as those common long-tentacled yellow polyps. Bought from different sources, but as long as it's yellow, it doesn't seem to do well in my tank. The grey masses usually have hundreds of copepods feasting on them, like a swarm of flies.

Funny thing is the other zoos that are brown are unaffected and doing well, multiplying in number too. Goniopora and sun corals are likewise unaffected.

Has anyone seen this strange disease before?

Here's how the yellow polyps are degenerating.

They turn grey and whither away. As of now I see hundreds of copepods feasting on the grey masses. Other things in the tank appear to be doing well.

Hrmz, copepods eat corals? Thats strange but at least you won't hv a shortage of pods in your tank for fishes...
