They're totally awesome fish! I've been looking for some more but haven't had much luck. They're not really picky on water parameters. I've read they do fine in fairly cool water, and mine is doing great in tropical temps. Once you get them off of live food they'll eat pretty much anything (Mine never did get on pellets). It's not too difficult to get them on dead food, a little starvation will do the trick. As you can see in Eds pictures, they have a pretty quick growth rate.
