The Clarkii Clownfish is a highly popular aquarium species. They are sometimes sold under the name of “Sebae Clownfish”, which is actually the species name of a very different clownfish. Full grown Clarkii Clownfish can reach a size of about 4 inches, and are territorial when full grown. This is a species easily cared for in aquariums and will accept a wide variety of foods. Most clownfish eat some algae in nature, and this should be included in their diet.

Clarkii Clownfish are the most widely distributed anemonefish in the world, and show a large range of color variation. They occur from the Caroline Islands in the east, west to the Persian Gulf, north to Southern Japan and south to the New Hebrides.

We grow two varieties of Clarkii clowns at ORA.  One of the varieties originates from the Solomon Islands, and fish from this lineage develop dark black flanks that contrast their bright yellow fins.  Clarkii are one of the least restrictive species when it comes to host anemones, and will associate with a variety of them.

Clarkii regularly produce nests of over 1,000 eggs, as often as 3 times per month.  Their eggs hatch in 7 to 9 days.  It typically takes 4 months for a Clarkii clownfish to grow to a seller-sized individual.

On rare occasions, Clarkii Clownfish will develop a highly desirable and interesting mutation in their eyes. A pale blue crescent appears in the upper part of the iris in the eye. We call these “Pearl Eyes.”
