Yellowbelly rockcod

Epinephelus marginatus

Key differences: Epinephelus marginatus (Yellowbelly rockcod or Dusky grouper) has a more uniform dark brown coloration, often with irregular pale blotches, and typically lacks the distinct small dark spots of E. andersoni. Its caudal fin is often truncate to slightly emarginate in adults, whereas E. andersoni has a rounded caudal fin. E. marginatus also has a more prominent notch in the preopercle.

Potato bass

Epinephelus tukula

Key differences: Epinephelus tukula (Potato bass) is a much larger species with distinctive large, widely spaced, dark blotches resembling potatoes on a lighter background. It is easily distinguished by its size and blotch pattern, which is very different from the fine spotting of E. andersoni.
