Acro Crab ID

You would absolutely throw this crab out vette?

Some people place in sump but I’d rather it not anywhere in my systems

This looks like a gorilla crab or some sort? Not coral safe. Beneficial acro crabs are generally very smooth. Any more pics? Is it hairy? Maybe keep in sump until someone can positively id it.

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…

doesn't look like a gorilla. Unsure if its a predatory crab though. Sump or toss IMO

don't forget the small but incredible pom pom crabs!

Carribean blue be leg hermits- stay tiny and great on algae and uneaten food
Caribbean red leg great scavenger
Porcelain crab also good

I put it in the tank! I put it in during lights off as my wrasse was sleeping….I’m about 90% sure my wrasse ate it the next morning.

in all honesty I believe it was a xanthid crab of some kind. But it may have been a commensal crab. In either case it could have been either beneficial or a detrimental pest.
