Demasoni, an interesting fish. Solo they are super aggressive. If kept in a community tank solo they will terrorize and kill most fish if the tank is under 125 gallons. Best if kept in a group in a community tank that is shorter than 6 ft long. Con-specific aggression makes them relatively peaceful to other tank mates when kept in a group larger than 5. They grow rapidly reach sexual maturity in 6 or so months if fed properly they can grow out in a 20 or 30 gallon. Its their aggression you need to watch most don't get more than 2 inches. I also breed these fish.
This is a great fish enjoy.
