Closed colony?

[AquaRxium]

Hey guys. For the past 2 months, my little eagle eye colony on top has progressively closed more and more. Any ideas/advice? Water parameters are stable. Nothing different. Could the zoas next to them be incompatible?

Have you checked them for pests?

I had hydroids on some other rocks that I put epoxy over. I'll check for those too. Thanx again for that link.

Some people have used a small dab of super glue gel to seal the tubes shut. You could also try smashing the shell with some pliers, but if you don't kill the snail itself it will grow back. GL.

I would say not a pest issue.
The other zoas would show signs of stress.

Hey guys. So I went around in the Rock and applied super glue to the tips of the worm shells. I noticed some of the zoas that have been closed for a while have what looks like algae growing over them? Is this in fact algae and what does this mean? Are the ones covered in algae dead now? I have plenty of cleanup livestock(blue hermits/peppermint shrimp/various snails).
