Zanzibar Archipelago - List of fishes

This damselfish lives in shallow waters of the Pacific and Indian Oceans. It feeds on algae and small invertebrates, and is recognized by its 5 black vertical stripes and the fluorescent yellow band under its dorsal fin.

Easily recognizable by its horizontal black and blue stripes on a yellow background, this surgeonfish is a compulsive swimmer. Large males control well-defined feeding territories and surround themselves with a harem of females.

The convict surgeonfish are common inhabitants of the lagoons and seagrass beds of the Indo-Pacific region. Fond of filamentous algae, these herbivorous fish are often found in mangroves and estuaries, at the edge of freshwater. They are easily recognizable by their vertical black stripes.

This fish is very shy and it is easy to approach it when diving. it eyes are hidden by transverse black lines. It has a black eyespot on the dorsal fin, which attracts the attention of predators to parts of its body where there are no vital organs.

The blacklip butterflyfish has a broad geographical distribution that spans from the Red Sea to the Galápagos Islands. Typically, it is found alone or in pairs in shallow coral reefs. It feeds on polyps of soft corals, particularly leather corals and broccoli corals.

The blue-green Chromis is a fish that lives in large schools above dense coral areas. At the slightest alarm, this swift fish takes refuge in the colonies of branching corals. The Blue-green Chromis is common throughout the Indo-Pacific region.

The common name of this species refers to the patterns observed in young individuals. Adults typically live among the arms of branching corals, while juveniles more often reside among the tentacles of anemones. These fish are omnivores with a carnivorous tendency.

In some languages, this fish is called the "birdmouth wrasse" because of its hopping swimming, its long pectoral fins and a long "nose". It is hermaphrodite and changes sex and color in it life. Juveniles and females have two colors, while males are blue.

The bluestreak cleaner wrasse feeds exclusively by parasitically cleaning larger fish and turtles. In the reefs, it coordinates a cleaning station, typically near branching corals. Particularly active at the beginning of the day, these small cleaner wrasses clean the gills and mouths of many fish species.

The palette surgeonfish sports a pair of venomous, erectable scalpel spines at the base of its tail, used for self-defense against predators. It primarily dwells in small groups within coastal reefs. Its electric blue color inspired the character of Dory in "Finding Nemo" and "Finding Dory".

The Emperor Angelfish is found from the Red Sea to the Great Barrier Reef. Juveniles hide under reef overhangs or in holes in outer lagoons, while adults prefer caves in coral-rich areas. These fish feed on sponges and form pairs for reproduction.

This squirrelfish is recognizable by its fine horizontal white stripes with silvery highlights on a predominantly red body. Like its counterparts, it is a nocturnal, exclusively carnivorous fish. It particularly preys on mollusks and small crustaceans living among the rocks.
