Found this small crab on my gorgonia that arrived today. Around 1 cm in size. Is it okay to put in the tank or will I regret it later?

The claws are pointy with white tips. I would love to have a large crab, but most seems to wreak havoc in one way or another.

They do look a bit more pointy. Red mithrax crabs can have whiter tips, too:

but the carapace on yours looks less knobby and the arms/claws a bit bulkier, which might mean this guy isn't into salads. @ISpeakForTheSeas Do you recognize OP's crab?

Unfortunately no - but I struggle with ID'ing red and brown crabs. I will say, though, the body shape looks slightly off for a Mithraculus sp., and I don't see the extra arm joint on OP's crab like you can see on those Red Mithrax crabs.

Personally, based on the body shape and arms, I'd guess it's not reef-safe. My best guess at a species (which is likely wrong) is Lydia annulipe.
 
I really hate killing stuff that comes with corals etc. Could it eat sps or lps, fish?
 
I've had great luck giving away hitchhiker crabs to locals after posting them with pics. One person drove to my office to pick up a gorilla crab because their daughter thought it was cute (I confirmed they knew to put it in their sump, not in their display).
 
It seems to prefer hair algea over artemia. I will keep it in a breeder box for a few days.
