Do crabs go rogue on zoas???

[glb]

Help! Some of my zoas are coming off their rock! They aren't dead and I've been able to put them back. I think my blue hermits and emerald crabs might be beating up on them. For several months, I had no problem. Has anyone else had this experience and if so, what did you do??

Yes, hermits, emeralds, and snails always knock frags off from plugs. Sometimes on purpose looking for algae under the glue other times on a drive by.

Yes all the time...lol! I just get out the super glue gel or two part putty and re-mount them.

I only put red leg hermit crab in my zoa tank to avoid this issue. The Electric blue is very rough on zoas.

I had 2 Halloween hermits in my 34g and that's it. Emerald crabs are the devil!

I have red, blue and black legs and they do the same.

depends on type of crabs. some will disturb it to forage for food

My hermits have blue legs with an orange stripe. They were in the tank for a while with no problem. Is it that they're bigger now? Should I remove them? If so, can snails work as the only cuc's in a nano?
