Aspect: | All parrotfishes sport a stong elongated oval body boasting large scales, prominent mouth with bill-like frontal teeth (hence the name) with which they bite away at coral. |
Population: | Quite common. |
Notable feature: |
Juveniles: hardly one inch-long, white with three black horizontal lines, transparent (almost invisible) fins. Initial (or intermediate) female phase: afore-mentioned black bars turn brown and fade, while fins turn opaque. Advanced Initial phase: body and fins gradually turn yellow while the lower longitunial brown line fades away (see sample amongst pictures below). Terminal male phase: generally blue-green body with characteristic bright yellow patch aft pectoral fin fading backwards, mauve to amber-edged dorsal fin and tail fin, green-bordered purple-blue line straddles upper snout and runs sidewards across the eyes to fade towards the gill area. |
Environment: | Swims around rocks and coral boulders from which it violently (as seen on one of the photos below) bites off algae. Builds a protective film bubble when sleeping at night under rock recesses. |
Behaviour: | Can be approached to about one or two metres. |
