I bought two banjo cats at the LFS the other day. The larger one pretty much does everything I expected him to do (lay around all day and move around mostly at night), but the other one I swear is on crack or something. When I first introduced them to the tank, they both just sort of half swam half drifted to the bottom and they chilled right where they fell only moving around to find cover. Well, after about an hour or so, the smaller of the two started swimming laps around the aquarium at a pretty high speed. At first we thought it was entertaining, since he roused my upside down cat out of hiding and proceeded to get chased for a little while. The upside down cat lost interest and went back to his hiding place while the crack head banjo just kept on swimming. He's been doing this almost nonstop for a couple of days now. I'm worried that he'll die of exhaustion. All my water readings are normal, so I don't think that it has anything to do with that. Anybody got any clues???
