The Red V-Tail Grouper (Cephalopholis urodeta) is found living near coral reefs and rocky areas of the sea floor throughout the Indo-Pacific from India to the Hawaiian Islands. They are a popular grouper species within the aquarium hobby due to their beautiful red color, moderate size and relative ease of care.
They are often sold by a variety of common names including the Flag Fin Grouper, Flag Tail Grouper, Banded Tail Sea Bass, Red Flag Grouper, Darkin Hind Grouper and Coral Cod. Red V-Tail Groupers do well within the aquarium environment as they have a very hardy disposition and a maximum size of about 10 to 11 inches, which makes them well suited for aquariums in the 90 to 110 gallon range or larger. Their smaller max size also makes them easier to pair with tank mates as their smaller mouths make them less of a risk to consume medium size or larger fish mates.
The Red Flag Grouper is known by many names including the Flagtail Grouper, Darkfin Hind, Banded-tail Coral-cod, and the V-tail Grouper. It has a red body, sometimes mottled with white. The two white stripes on the caudal fin (tail) appear to form a "V."
A 180 gallon or larger aquarium is required due to its size and feeding habits. It is an extremely aggressive fish and may eat its tank mates as well as crustaceans.
