I have been reading about these things and I have wanted one for a long time, so I figured it was time to risk it. Any pointers? I have him aclimated and in the tank now, he seems to be pretty active, but leaving everything else alone. He finds something to crawl into and just hangs out.

Is he going to eat my large purple Lobster(don't really care-he never comes out)? they are both nocturnal.
