Angelfish

Angelfish

Angelfish are some of the most brightly coloured fish on the reef, having bright blues and yellows in different patterns across their body. They are recognized by their big pouty lips and the spine on their gills.  They are usually seen alone or two or three individuals close together.  Their behaviour is skittish and they tend to stay close to the rock and substrate where they have somewhere to swim off to and hide.

Semi-circle angelfish are dark blue to green in colour with discrete blue spotting. They are easily identified by their neon blue outline, which looks like it is glowing when it catches the light. Their pouty lips tend to be a lighter shade of green/yellow. They tend to be seen alone, closer to the reef in sheltered areas. (up to 35cm)

Emperor Angelfish (Pomacanthus imperator)

The Emperor angelfish is a brightly coloured fish with blue and yellow stripes and a yellow tail.  They have a distinctive eye band as adults which helps to confuse predators.  They have a thick blue bar running behind the head. They are generally found closer to the boulders, and are present either solitary or in pairs. They look completely different when they are juvenile; It takes about two years to change completely They eat sponges, which contain needle like silica (glass like fragments). To stop these becoming lodged in their body they coat them with a slimy mucus. They are very territorial and will males violently attack other emperor angelfish coming into their territory – which can 1000-2000m2. They can reach 40cm. When threatened and during mating they make a grunting sound. Both males and females change colour during courtship and mating.
