Gorilla/Emerald crab? I got him on the first night

[LMDAVE]

My tank is in it's early cycling stage, started with two pieces of live rock with rest dry rock, and now starting now to see some hitchhikers. Saw this one's black tip claws poking out the live rock hole by chance yesterday, a quick search told me it might be a gorilla crab and best to get him out. A friend told me about the glass trick, so I did that last night with a piece of raw fish on the bottom of it. Sure enough he was in the glass the next morning. Now what? I don't have a sump on my system.

Either you should find someone with a sump or get rid of it meaning kill it or maybe a fish store will take it. But I would try to give it to someone that has a sump or a fish store
