I've got a resident crayfish in here, which is keeping me from bringing other tankmates in it, as I'm sure he'll harass them. He's kinda mean! He looks at me when I come around, but when I try to net him, he's gone. >_<
I tried to net him because I'm going to put CRS in here, as the title presumes, but he's preventing that.
I will say I had to move this tank from college to home for a month, and it proves to be a very easy tank to move, whereas long tanks are a PITA to move.
