That's the thing, we didn't do anything really! We did give him/her a heater, pump but it just pinched the wires and the water went BLACK! And we had it in a small fish-tank with a lid, but he decided that the tank wasn't good enough. On a few occasions, he escaped from the tank and wasn't seen for weeks! The last time that he disappeared, it was summer and really hot. We thought he'd died, but he came home (till can't understand how he lived for Sooooooo long!) Bet you can guess its name, right?
