How to recognize the heavybeak parrotfish ?

The Chlorurus gibbus is a heavybeak parrotfish with a yellow/red coloration evolving into green as it ages. It can reach up to 70 cm in length and live at least 14 years.

In the initial phase, the Chlorurus gibbus has a yellow body with green/blue edges. Its abdomen, pelvic and pectoral fins are dark red with a green edge.

In the terminal phase, the body is gray-green. The scales are surrounded by a pink/orange line. The thorax is blue-green and its abdomen is pale yellow/green with 2 slight stripes. Its head is purple and its lips and eyes are lined with blue as well as its cheek.

The dorsal and anal fins are a succession of lines: blue, pink, purple and green. The bump on its snout only appears in the terminal phase.

Sexual dimorphism

Fishkeeping

Not recommended

We do not recommend keeping this species in an aquarium. It has unpredictable needs which, if not met, generate significant stress, potentially leading to a shorter life expectancy, an interruption of its growth or the development of pathogens.
