Holacanthus africanus

Juvenile Guinean angelfish have dark blue bodies with bright yellow lips and tail, narrow vertical pale blue lines on either side of the eye, and a white vertical bar in the middle of the body. In the adult, the blue becomes an olive green, the white vertical bar becomes yellower, larger, and less distinct, and the caudal peduncle darkens to a near-black. Some yellow areas may remain on the edges of the dorsal and anal fins. A dark ocellus is visible behind the gill cover.[3] The maximum adult length is around 45 cm.

The Guinean angelfish has a non-specialized diet.[4] It feeds primarily on sponges, but also on tunicates, jellyfish, and soft corals as well as algae and plankton.

Guinean angelfish inhabit rocky areas and reefs from Senegal to the Congo, including the Cape Verde islands and São Tomé. It is common off the coast of Ghana.[5] They have also recently been found in the waters around Sicily and Malta in the central Mediterranean.[6][7]
