I have one that's about 16-17" and really fat.
He eats primarily market shrimp, but recently stalked, killed, and half ate an 8" pink tail chalceus. He also recently shredded a big frontosa.
Anyone else have theirs turn angrier as they get older?
I've tried to keep him with other ornates and bichirs...no luck. It looked like battle of the dinosaurs - with the vanquished hiding in the surface plants.
