Coral Grouper

Coral grouper are vivid red-orange fish that sit motionless on coral heads around the cave entrance, blending with the encrusting red sponges in the lower-light conditions of the cave surroundings. These ambush predators rely on camouflage and patience rather than pursuit speed, launching explosive strikes at passing damselfish and wrasse. As moderate apex predators on the shallow reef, their presence in healthy numbers is an indicator of good reef condition and limited fishing pressure.
