i got mine at petco, they sell ones that get up to $30 it looked like but they were full grown. i am not sure what breed mine was. i wanted to get a younger one so i went for the one titled baby boy, they had some baby girls as well. i like the males more cuz of the big flowing fins.
i did use it a little warmer but not by too much the tank was coolish so i tried to keep it the same. i got a heater that regulates itself at a constant 75 instead of overheating and crapping out permenantly, which is annoying for $16 the $20 one that keeps the heat at the same level is what i wanted. it has an LED light that lights up when it turns on to keep the water temp at 78 F and shuts off when it isnt.
