Today I recieved a large specimen (7 or 8"). When I went to get crickets there was an isopod in the cricket tank. (It looked like a small brown caterpiller) I asked for it as well. I took it home and through it in the Critter Keeper with my pede. It ate it within 2 seconds. How am I supposed use Isopods to keep it clean if I can't keep Isopods alive for more than a second? lol
