The members of the family Pomacanthidae are generally know as angelfishes and, like their nearest cousins, the butterflyfishes, are regarded by many divers and aquarists as being amongst the most beautiful and majestic fishes in the sea. The majority of species occur on shallow reefs in coral, algae and sponge zones, most going little deeper than about 30m but where conditions are pristine and water is very clear, many species go much deeper and few species only live deep (over 100m). Angelfishes feature a large and distinctive backward-protruding spine from the lower corner of the gill-plate (cheek spine) from which the family name was derived. This cheek-spine is diagnostic for all the species , even at juvenile stage, and readily separates any angelfishes from butterflyfishes that may be similar in shape. Mot angelfishes are robust with compressed, ovate to rhomboid shaped bodies, covered with small or tiny scales, and have a continuous dorsal fin. The mouth is small and jaws are set with many small, usually tricuspid teeth that are used for grazing algae or scraping sponges and other sessile invertebrates. Few species combine their diet with a variety of foods and some are planktivores.
Place of origin:Western Indian Ocean
Appears to be restricted to subtropical waters from just south of Bazaruto in Mozambique to East Londo in SA.. The Tiger Angelfish is moderately common on rocky offshore reefs (Aliwal Shoal) at 20-50m depth, but usually seen deeper than 25m where sponges are more common. Often occurs in small loose groups. A timid species which withdraws to deep crevices or swims away when approached. With no other similar species in its range, this species is readily identified. Top half of the body is black with wavy yellow lines, grading to a uniformly pale grey ventrally, head and breast are sooty dark. There is a black spot behind the head. Dorsal and caudal fins have a narrow light border. Juveniles with fewer 'tiger-stripes' and a yellow-edged black ocellus at base of soft dorsal fin. Length to 24cm.
