The Canary Damselfish is native to reefs of the eastern Atlantic islands including the Canary Islands (after which it is named),
Madeira, the Salvage Islands, Cape Verde Islands and the Azores plus a part of the West African Coast around Senegal.
The juvenile is more colourful, being dark blue with its neon purple head markings and neon turquoise fin edges.
The adult is browner without the head markings but retains the blue fin edges. All but one on this page are juveniles which get
left behind in tidal rock pools when the tide goes out (as these have).
The adult, above left, grows to 15cm long. It is an omnivore. Some classify the fish in the Abudefduf genus
with the striped Sergeant Damselfishes.
