About this species

The squaretail coral grouper is a species of marine ray-finned fish. It is a grouper from the subfamily Epinephelinae, which is part of the family Serranidae. This family also includes anthias and sea basses. The squaretail coral grouper is also known as the spotted coral trout or the squaretail coral trout, and is fast-growing, short-lived, and early-maturing. However, due to the continued decrease in its population, it is now classified as vulnerable, as it continues to face threats from human activity.
