Care

Clark's Clownfish are relatively easy to care for, making them suitable for both novice and experienced aquarists. They thrive in well-established aquariums with plenty of hiding spaces and a stable environment. They are omnivorous and will accept a variety of foods, but a diet rich in marine-based proteins and vitamins is recommended to maintain their health and coloration.

Reproduction

Like other clownfish, Clark's Clownfish are protandrous hermaphrodites. They form monogamous pairs, and the dominant individual will become female. They lay their eggs on flat surfaces close to their host anemones, and the male will guard and tend to the eggs until they hatch.

Symbiosis

Clark's Clownfish form symbiotic relationships with several species of anemones, including @species:entacmaea-quadricolor, @species:stichodactyla-gigantea, and @species:heteractis-magnifica. They benefit from the anemone's protection and in return provide food scraps and aeration through their movement.

Habitat

Amphiprion clarkii is found in a range of habitats from shallow lagoons to deeper outer reef slopes. They are distributed across the Indo-West Pacific, from the Persian Gulf to Western Australia, and up to Japan.
