V-Tail Grouper - Cephalopholis urodelus: The V-tail Grouper is known by many names including the Darkfin Hind, Banded-tail Coral-cod, the Flagtail Grouper, and in the commercial trade as Red Flag Grouper. It has a red body, sometimes mottled with white. The two white stripes on the caudal fin (tail) appear to form a "V."

Its red body reflects sheens of grey and green in different lighting. The "V-Tail" portion of its common name comes from the two distinct nearly-iridescent stripes on its tail fin. With the potential to grow to nearly a foot in length, the Red V-Tail Grouper should be kept only in larger aquariums. In the home aquarium, it has little interest in corals, but may likely dislodge corals as it darts after its next meal. V-tail Grouper may eat any fish that will fit into its mouth. Crustaceans, being part of its natural diet, will likely be eaten. This Indo-Pacific native is an opportunist predator. It welcomes a diet of smaller live fish upon which it can prey with a sudden, unexpected burst of speed and frozen krill and other meaty prepared foods. Because "high input" fish are also "high output" fish, an excellent filtration and biological system should be in place prior to introduction. V-tail Grouper should only be kept with other aggressive carnivores such as Triggers and Eels.
