Another photo that was taken at the aquarium in the Pretoria Zoo and it is the first photo of this species on TrekNature. As I said with my previous aquarium fish posting, I quickly realised that this kind of photography is not as easy as I anticipated. The reflection and the marks on the glass was a major handicap that I quickly had to figure out otherwise I could forget to continue with the shoot. The density of the water, the surface of the fish (which vary from very bright to rather dark even within the same fish), the general activities of the other fish in the tank, the colourful and close proximity of the water plants and coral - all added to a difficult shoot. I needed to be very sure that I knew exactly how to interpret the LCD on my camera, otherwise I might found that all the photos that looked so good on the LCD actually were either over exposed or under exposed. Sorry, that would have been too late, because once I was back home the aquarium is 700km away and there is no time for a re-shoot. The workshop is just a splash of colour in one of the tanks at the aquarium.

Description
The similarity between juvenile forms of this fish and the Koran or Emperor angelfish can be a source of great confusion! In the Koran the white stripes are slightly curved or shaped, but they are much more curved near the tail forming a completely closed ellipse in the Emperor. In the Bluering Angelfish the white stripes are almost straight, only the ends curving inward slightly towards the tail. Diagonal blue lines on sides, a blue ring behind the eye, and a white tail. Up to 45 cm.
Distribution
Indo-West Pacific: East coast of Africa, throughout Indonesia and New Guinea to New Caledonia, north to southern Japan.
Habitat
Inhabits coastal rocky reefs to at least 30m. A non-migratory marine fish. Adults are often found inside caves where one male defends a territory with two to five females living with the male.
Food
Omnivorous, eating benthic invertebrates such as zooplankton, sponges, tunicates, coral polyps, algae, weeds, and nektonic fishes. Source.
