Honeycomb grouper
Epinephelus quoyanus

Family Serranidae
updated Oct 2016

Where seen? This boldly patterned but well camouflaged fish was seen at Tanah Merah. Elsewhere, they are seen in silty reefs, in shallow and intertidal waters.

Features: To about 35-40cm. There are many species of groupers with a mosaic-like pattern. The Honeycomb grouper is distinguished by having less dense spotting, larger polygonal spots, thin or no white margin on the tail. It also has oblique dark bands just below the pectoral fin base. Often seen resting on the ground with its enlarged fleshy pectoral fins held outward.

What does it eat?
It eats crustaceans, fishes and worms.

Human uses: It is among the common fishes eaten in Singapore. Here, these fishes are sometimes reared in floating cages from fingerlings (young fishes) that are imported from neighbouring countries, until they reach marketable size.
