Can you give me the name of some large predatory fishes that can breathe or can survive in extreme low oxygen cuz of their unique breathing or even without air pump? I know of arowana, arapaima, gars, tarpons, snakeheads, aba aba knifefish, clown knifefish, bichirs, lungfish, bowfin, hoplias and giant gourami. I really wanna know more about this, since I just realised that tarpons can breathe air today. I wanna know if there are more fishes that could breathe air, but they're underrated or most people don't know that they can breathe air.
