Its really fun to watch them take sticks off the surface. They are so fast and the water boils when they eat. Almost like Piranha.
When my armatus wouldn't eat when I first got him, I tied fishing line to a piece of talapia and tossed it in the tank. The current + me moving it around to mimic a wounded or dyeing fish. He had interest right away, and ate after a week.
