Tag: Blue-Ringed Angelfish (Pomacanthus Annularis)

The Blue-Ringed Angelfish (Pomacanthus Annularis) is one of only two Angelfish commonly found in local waters, the other being the slightly larger Six-Banded Angelfish (Pomacanthus Sexstriatus).

Easily identified with its overall purple/yellow colouration, white tail and upward curving neon blue lines.

There is a neon blue circle above the eye from which this species derives its common name.

One interesting feature that appears to differentiate individuals found in local waters from their counterparts on Thailand's west coast is the lack of a trailing filament from the back of the dorsal fin. This filament appears to be common on west coast individuals but i have yet to see it on any individual found in the Gulf of Thailand.

The Blue-Ringed Angelfish grows to a maximum size of around 45cm and feeds on a diet consisting of algae, sponges and live coral flesh on occasion.

They are a very common species, usually found in pairs at all of the main diving and snorkelling sites we visit.
