honestly the fish i have, i belive its a salminus brasilianses, since they are from brazil, smaller head. typical dorado, is salminus maxilosus, big mouth!
im not too sure bout the scientific name for my dourado but its what people call the golden dourado.. it's super aggressive and no successful comms so far... it has killed several tinfoil barbs, silversharks, flatfish and it nearly killed my african pike as well...
