Zoanthids excretion

[costello303]

I have had some zoanthids in my nano tank for a couple of months now, but for the past couple of days they have not been looking too healthy.

They seem to be excreting some sort of discharge from the head of the polyps, I have read the threads about the palytoxin and worried that it might be this. Not sure if this is related but a Hitchhiker swiming crab has made the coral its home for the past couple of weeks.

Thanks

Sounds like the crab is irratating the coral to death to me. I would go for an extraction and see how the zoos recover.
