They are really turning out very nice. I got them from Jeff Rapps this past october at about 2" to get some breeding action. As for the setup I wanted it easy to keep clean since they are so messy....so far it has been perfect. Just wish my 2 fav ones would have hooked up. I wonder how long untill i have eggs. They have been dancing all day next to that rock in the right front corner. They moved it there...
