Small crab that came from live rock not seen till now!

[Deyan]

Hi, folks. So, I found this little fella just now and never seen him before.. bought live rock from live rock and reef while back. I am just wondering what type of crab he is.. whether he is reef safe or not! Seems ok for now.. just on the algae chopping away. Thanks in advance!

There is surprisingly little information specifically about coral crabs in aquaria. Every now and then some hitchhikers arrive on our aquacultured and wild corals and we are able to gain a bit more…

It appears to have the extremely original name of Hairy Crab

I have some of these in my tank and they get about 2 inches. They dig sometimes. Came on TBS rock.

That's a cool looking crab

A good idea would be to sump him until you find out what he is. Most often hairy crabs will start chomping on things they shouldn't.
