Exactly how dangerous are Arowanas to other fish the same size as them? Or bigger?
I mean, he's gonna be with a Pacu that's probably 20 times bigger than he is (not in length, just in general bulk) (ps: don't worry, this fish has never been fed feeders in its entire life, and just to be sure I dropped a couple of small guppies in there once and she didn't even bat an eyelash, so I know smaller fish are safe around her), but if they were the same size, how much can he actually hurt another fish? To death?
