I dont know about you guys but I just love watching my rbps school around the tank together. Its also still amazes me watch them hunt down feeder fish when I put them in the tank. It seems like they swim a few laps around the tank first to get a game plan down and then wham the feeders are gone. I also love watching their silver speckles flicker under the light when they swim in the powerhead. They spend most of their day doing this, looking like an amusement park ride for them. They swim up the current from one end of the tank to the other and then when they get right up by the powerhead the float back to beginning in the current and hit it again. I have kept all kinds of fish, cichlids, saltwater and I have the say that piranhas are definitely my favorite so far. Just my opinion.
