Help!!! Under Attack

[kingnai]

How do I stop the hermit Crabs from eating the base of my colt coral? There are areas on the stalk that are dug out and the coral is not doing so well.
Any Advice???
Only other fish is a damsel that I can't catch to get rid of and a goby, and a cleaner shrimp, Brittle & Serpant Stars

See if you can see a tiny white nudibranch on the white area.

Ok I am kinda new whats a nudibranch? and what does it look like?...

Nudibranchs are the scientific name for sea slugs. There are many different kinds, but several species eat corals. This could be the problem, but just in case, what are your water parameters, such as salinity, PH, Alk, nitrates, ammonia, etc. How long have you had the colt? What kind of hermit crabs do you have?

NO Nudibranch...
I have blue and red leg hermits...
All Water Parameters are good...

Blue-legged hermit crabs are known to dine on other tank inhabitants.
