Ya know I wondered how they would feed and mine will eat anything day one they hunted down a dozen ghost shrimp that were for a baby RTC lol I was not aware they would eat live things but also they ate carnivore tabs and hikari cichlids gold that night idk where it all goes well.... I guess they do move a lot lolI have 4 of the pictus in my ray tank. They are all about 4" and active all of the time. Two of them eat about anything, the other 2 are picky. I have always read that they do better in groups. IME, they are more solitary. Each one has it's own "space" in the tank. If one strays too near someone else's area, they get chased away. I also had a 4 line pim in the same tank. That fish was a beast. Very peaceful with others, but spent most of the time hanging out under the drift wood.
