Singapore has four species of angelfish that I know of:

1. Chaetodontoplus mesoleucus (Vermiculated Angelfish)

A common fish on our reefs; not abundant, but usually a pair can be seen on a dive. Commonly mistaken for a butterflyfish.

2. Pomacanthus annularis (Blue Ring Angelfish)

Not commonly seen on a reef; there used to be one resident at the artificial reefs I studied off Pulau Hantu. Adults have a distinctly white tail and blue diagonal stripes; juveniles have alternating iridescent light blue and dark stripes.

3. Pomacanthus imperator (Emperor Angelfish)

Only seen once before at an artificial reef site off Pulau Hantu.

4. Pomacanthus sexstriatus (Six-barred Angelfish)

Not so common on our reefs, but exciting to see them when they appear. Typically wary of divers, they will stay out in the open and eye-ball you if you keep calm and keep your distance.

Anyone know of more?
