Clarkii Clownfish (Amphiprion clarkii)
The Clarkii Clownfish, Amphiprion clarkii, is a bold and highly variable Indo-West Pacific anemonefish recognised by its dark brown to black body, contrasting white bars and yellow, orange or white fins. Also known as Clark’s Anemonefish or the Yellowtail Clownfish, its appearance varies considerably between geographical regions, with some individuals displaying much more orange or yellow than others. This adaptable species naturally lives among the tentacles of several host anemones and is one of the larger, more assertive clownfish commonly maintained in marine aquariums. Its hardiness, striking markings and engaging behaviour make it a popular choice, although mature pairs can become strongly territorial.

The Clarkii Clownfish is a striking addition to my marine tank. Its vibrant colors and active behavior are captivating. I’ve paired it with a healthy anemone, and it spends most of its time near the tentacles. Only issue is that the male became quite territorial after a few weeks, so I now keep it alone.

Great fish with bold markings. The yellow fins stand out well in the tank. I’ve had it for three months and it’s very active, especially during feeding times. It’s not the quietest fish, but it’s worth the energy.

Highly recommended for experienced marine aquarists. The color variation between individuals is impressive. My fish has adapted well to the anemone and shows daily interaction with it. A bit aggressive at first, but settled after a month.
