Tomato Clownfish

Clownfish or anemonefish are fishes that, in the wild, form symbiotic mutualisms with sea anemones and are unaffected by the stinging tentacles of the host anemone, see Amphiprioninae § Mutualism. The sea anemone protects the clownfish from predators, as well as providing food through the scraps left from the anemone's meals and occasional dead anemone tentacles. In return, the clownfish defends the anemone from its predators, and parasites. Clownfish are small, 10–18 centimetres (3.9–7.1 in), and depending on species, they are overall yellow, orange, or reddish or blackish color, and many show white bars or patches. Within species there may be color variations, most commonly according to distribution, but also based on sex, age and host anemone. Clownfish are found in warmer waters of the Indian and Pacific oceans and the Red Sea in sheltered reefs or in shallow lagoons.

This species is found as far north as Ryukyu Islands, Japan, to the South China Sea and surrounding areas including Malaysia and Indonesia. Some authors report that this species is associated with a single species of anemone, the bubble-tip anemone (Entacmaea quadricolor). Other authorities report that it may be associated with the sebae anemone (Heteractis crispa), as well.
