Gorilla Crab

[GeorgiaMan]

I have added live rock and today I found what I am pretty sure is a Gorilla Crab. How bad is this animal to have in my tank? He is currently living under a bubble tip anemone and is quite small (Dime size or smaller from leg tip to leg tip.) I am building a fish only with live rock tank. I have only found bad things about them on the web. Any advice would be appreciated.

It’s hard to tell without a picture. Gorilla crab is a common name and can be referenced for so many species. Can you find or give a picture?

I tend to be live and let live about these things, but I evict any crabs that look hairy and have large, black-tipped claws. It may be small now, but is likely to eat some favorite specimens later.
