Zoa Melt

[tubbsiewubbsie]

So I'm not a Zoa guy but I've got a few free on a couple of orders. They've been in my tank doing fine for around a year. Over the last 2 days one type has all but entirely melted away. Now it looks like 1 of its neighbors has started the same thing.

Anybody know what might cause Zoa melt. Euphyllia and SPS look fine.

Anything we can’t see that may be sending sweepers out at night and stinging them? Leather allelopathy?

I do have a small war coral 3 or 4 inches away. Its been there for months but maybe thats the culprit?
