We love our pacu. They really are dog-like in behavior--seeking attention, pushing each other out of the way to be petted. They watch us all the time. Sometimes it seems like they're thinking, "why do we have to be in this tank?"
After Liz posted that she had fed her pacu potato slices, we tried it. They went crazy over the potato. Leonardo managed to suck in a whole slice that got rolled up. He was swimming around with a potato "cigarrette" stuck in his mouth. He looked so comical. Didn't know if I'd have to do the Heimlich Manuever on him! I ran and got my camera. Here's the end of the feeding. It is very evident that they have very big personalities. Leonardo is quite a rascal who always makes eye contact with us. You will notice the missing scales on Adonis. These big boys have vivid imaginations and sometimes freak out and go berserk as they try to escape from an imagined predator. Even in the bare tank they manage to cut and scrape themselves by hurling themselves into the tank lids as they attempt to escape from an unseen monster. One big crash into a wall or a lid, and they come back to reality and become jolly jovial giants again. In this video, Adonis gets the best of Leonardo the bully, but Leonardo gets the last potato chip.
