Was a process to get mine to eat... to begin with all they would eat was live bloodworm. Mixing live with frozen they eventually ate frozen. Then soaked frozen prawn in the bloodworm and they eventually took that. Now they will take tilapia/pangasius and 2 of them will eat massivore- though only when the lights are out. If you can get them, mine also took live river shrimp from the start... Of course other people bring the, home and they eat pellets from the get go... so I guess it also depends on the individual fish!
