Clark's Anemonefish (Amphiprion clarkii)
Kareko Batu, Lembeh.
Lembeh's anemonefishes always have at least two bigger ones defending the anemone and the rest of inhabitants. they are very fierce and will even bite you (not much pain but you can feel it!). They come high up from the anemone and chase you away, like these two were trying to do with me. It reminds me of the plovers that fake a broken wing to also drive you away from their nest location.
Clark's anemonefish or the Yellowtail clownfish 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.
