AHA!! It's a mantis!

[karazy]

there's a few ways to get him out. you could make a trap out of a pop bottle like you would for fish and just put a table shrimp in it to make it less resistible.

or you could try shooting some RO water into his hidy hole and then catch him when he gets out.

or you could try taking the whole rock he's in out and dipping it in RO water until he comes out, then just throw him in your sump, and if you dont have one i guess you could take a ziploc container, poke some holes in it, put the mantis in and then just leave it in your tank.
