Looks how to spot one

Coloursred to orange with dark mahogany or black sides and a white head barNew Caledonia form: red body, black saddle, yellow or orange fins, blue head bar2 3

Personality what they are like

Similar in character to the tomato clownfish: confident and territorial once settled in, and keen to guard its home.3 2

Daily activity how busy a day looks

Stays close to its host anemone, most often a bubble-tip, or to a favourite spot in the tank.1 2

Grooming and care the hands-on bits

A fully marine reef fish that accepts flakes, pellets and frozen foods. It can become territorial once it has settled into a tank, so tank mates are best chosen with that in mind.2 3

Home where they are happiest

A saltwater aquarium with rockwork or a host anemone. In the wild it lives in lagoons and on outer reefs at about 1 to 18 m, usually with the bubble-tip anemone (Entacmaea quadricolor).1 2

Food basics what goes in the bowl

An omnivore. Wild fish eat planktonic copepods, small crustaceans and algae; in aquariums it takes flakes, brine shrimp, mysid shrimp, algae and pellets.1 2

Company who they like around

Lives in small size-ranked groups led by one breeding female and one breeding male, and forms close pairs when breeding.2 1

The story where it all began

Bleeker described the cinnamon clownfish in 1852. It is found across the western Pacific and has been bred successfully in aquariums, with captive-bred fish now offered in the hobby.1 2 3
