Hitchhiker crab

I found this crab a couple month back as probably 1/4 the size that it is right now( it's now about an inch). I first found it on a bubble coral and right now I just caught in on my Duncan coral. If anybody knows if this type of crab is harmful or if it's not a big deal please let me know thanks.

Type of Xanthid crab. Sometimes called gorilla crab. I would take it out. I put mine in the sump. Usually pointy tip claws are bad

Xanthid, sump him. They can live off basically nothing, but can eat anything, and will eat everything. As a sump pet, they'll clean up any gunk that makes it to the sump.
