Hermits in Stylo

[renko]

Hermit crabs keep crawling into a recently added Stylophora. The Stylo looks healthy with no dead areas. Is this normal. I can't imagine its a good thing for the coral. Any suggestions?

Mine do that when they're trying to molt. Make sure you've got spare shells for a larger crab. And don't worry too much. I used to have fits over it, and then I realized they weren't doing any damage. They may park there for a week, until the new shell hardens, particularly if they're breeding females, in which case they may release their young from that position some night.
