Heres my setup, i have a 3.5 and a 10 gallon aquarium. If i get one pair of cacatoides and breed them in the ten gallon then take the male out and put him by himself in teh 3.5 would this work. Keep in mind that the tanks will be fairly dense with plants and caves(made out of slabs of slate). Kris _________________________________________________________ DO YOU YAHOO!?
