I have one I bought before I found AC, and he's doing great. I have no idea what he eats, as I've heard they don't eat much algae and I don't have much anyway, yet he stays on the walls all of the time . I might put him in the 15g I'm about to set up and add a pair of filters, maybe keep the temperature down a bit. If I can find any, I'll get him 2 or 3 friends next time I go up to Halifax to stock up. I've had him a while and he's only about 1.8" long. I'm hoping in the new tank with friends he'll come out more, because I plan to put some river rocks in there. I'm not sure what kind of substrate they like, because he's only touched to sand once that I've seen and has only ventured onto the driftwood twice.
