The Clarkii Clownfish or the Yellowtail clownfish (Amphiprion clarkii) is a widely distributed clownfish. It is found in tropical waters, in lagoons and on outer reef slopes, from the Persian Gulf to Western Australia and throughout the Indian Ocean and Pacific Ocean as far as Melanesia and Micronesia, and as far north as Taiwan, southern Japan and the Ryukyu Islands.

The Clarkii Clownfish is a spectacularly colourful fish, with vivid black, white and yellow stripes, though the exact pattern shows considerable geographical variation. There are normally two white bands, one behind the eye and one above the anus. The tail fin may be white or yellow, but is always lighter than rest of the body.

The Clarkii Clownfish are a popular aquarium species. They are omnivorous, and in the aquarium will readily eat brine shrimp. They will regularly host in many sea anemones in the home aquarium.

The Clarkii Clownfish, a.k.a. Sebae Clown, is a beautiful Clownfish that has a higher profile than most clownfish. These Clowns have a yellow-orange body with vertical white bands along their body. They do extremely well in the aquarium and are very peaceful. The Clarkii Clownfish does not need an Anemone to survive, but will accept many different Anemones as its host, including corals. The Clarkii Fish is probably the least picky when it comes to Anemones and will accept Carpet Anemones, Bubble Tip Anemones, Sebae Anemone, or Long Tentacle Anemones as its host. These fish will accept most fish foods and are perfect for reef tanks. More than one can be kept in the same aquarium.

The Clarkii Clownfish have a very distinct swimming motion that is different from most fish. This is likely passed on through their genetic makeup from centuries of wiggling within the tentacles of Anemones. As the Clarkii Clown Fish wiggles within the stinging tentacles the Anemones mucus is likely smeared over the Clarkii’s body, which then protects it from additional stings. The reason that this theory is believed over others is the necessity of the Clarkii to re-acclimate itself after it has been awa
