New York city...I live on LI...How deep on water? right now I have a very sinple setup about 3-4 inches deep water with some rocks and floating wood for them to go on, this is only for now. In a week I wanna get them a nice tank, I was hoping I can make the water pretty deep so I can get a filter and as far as filters I should prolly aviod ones that are too strong correct? so it doesnt hurt them. So Im gonna try to redo their little home to make it a little nicer for the poor guys. Thanks for all the help.

P.S. Will they eat small feeder fish?
