Wolf Fish

any of the larger triggers,but freshwater i would say red SH or adult male umbee!

 

[Russy Pelican]

IMO for size the toughest fish are Western mosquito fish and Fairy Cichlids (brichardi).

That's a brilliant guess. Here I've been thinking about undulated triggers, snakeheads, and such... then I remember these tiny terrors that will shred much larger fish.

If convicts grew as big as a rhom or a snakehead....holy shoot! That would be the most aggressive fish ever.

adult red devil would be the my vote. my had my red devil for 9 years and I had keep him with almost any fresh water fish before including fahaka. Mine never back off from a fight.
