New Wolf fish questions (hoplias mala)

[quasar]

Thanks for the help guys

On another note, I saw him breathing heavy today for no reason at all. All the other fish are fine, but i noticed he was bloated from eating a 3" goldfish that's been living in the tank for a few weeks, could this be why?

guess he is just stuffed from the goldfish feast.
