It may work, for a very short period. People have commed Dorado, atf, and mala in massive tanks, but in a tank this size it won't last long. Atfs are very fragile at a small size, the wolf, mala or artc would destroy it. Also artcs are very aggressive, and as they use the bottom of the tank most, it would fight the mala, and depending on which is bigger and wants it more , one would most likely die. Take out the artc and there's a small chance, but all these fish are known for there aggression. One fish snaps and you got an expensive accident.
