Bengal sergeant
Abudefduf bengalensis

Family Pomacentridae
updated Aug 10
Where seen? This fish in pajamas is sometimes seen in small groups in pools at low tide on some of our shores, among coral rubble near reefs. It is quite a nervous fish and hides in crevices among coral rubble at the slightest sign of danger.

Features: To about 14cm, those seen on the intertidal are much smaller, about 4-6cm long. With 6-7 black narrow bars across a yellowish body. The tail has rounded lobes and is plain (there are no horizontal bars on the tail). There is no spot near the base of the tail. It is sometimes called the Narrow-banded sergeant major.

Similar fishes have fewer black bars (5 bars for A. vaigiensis and A. sexfasciatus).

What does it eat? It feeds on seaweeds, snails and small crabs.

The fishes are said to be highly territorial.
