I had one for a while and adored him! He was a nice high green, named Ozzie, and got about as big as a silver dollar before my lack of knowledge did him in. I thought they hibernated and so did not attend to him for about two months before I asked a knowing friend and found that he was 'trapped' in an unshed skin. I soaked him fast and got the skin off... but the lack of nutrition and oxygen had been too much.

I fed my guy mostly inverts with the occasional feeder fish for variety and amusement. It was so fun watching him hunt those fish.
I miss him, but don't trust myself, or the cold and dry of CO, enough to get another one...
