Appearance
The adult rock beauty is mostly yellow, turning blue toward the tail. The tail itself is yellow. The pectoral fins and ventral fins are yellow, and the lips and the edges of their dorsal fins and anal fins are dark blue. The adult measures up to 10 inches.
Distribution
The fish inhabits reefs from the tropical western Atlantic Ocean to the northern Gulf of Mexico. It can be found at depths between 3 and 92 metres.
Food
The rock beauty feeds primarily on sponges. It may also eat tunicates, jellyfish, and corals, as well as plankton and algae. In home aquaria, keepers have had limited success with diets of meat- and algae-based fish foods. The fish requires sponges to survive.References:
