Ery ery are wild caught and like all wild fish highly aggressive/predatory... Might shred any small tank mates. Stick with a species tank for the wolf if that's what your hearts set on.
The only way you can do a predator/aggresive comm is if the fish are captive bred/raised.
So if I introduce the cats first and let them grow, and then introduce the nandus, and introduce the wolf last, would that make any difference?Hum not necessarily... If they are of similar size (as in small) when they start and grow together it can work in a BIG tank
I'm no expert on wolf fish, but I can tell you that since they are wild caught, they will be more aggressive, and still have the instinct to kill.So if I introduce the cats first and let them grow, and then introduce the nandus, and introduce the wolf last, would that make any difference?
