But as the fish appears to have turned that way, it is unlikely to reverse. What nature programs into a fish species is not going to change. I would return the fish, unless you want fish destruction in your aquarium. As mentioned in our profile, this fish is often overly aggressive with fish that have vertical stripes, such as angels. Always thoroughly research any fish species before aquiring it; this not only saves you trouble, it is safer for the fish.
Well I bought him for my fiancees tank which is just monster fishes no angels or anythign with stripes
