Thielle's anemonefish
Amphiprion thiellei (Thielle's anemonefish) is thought to be a naturally occurring hybrid anemonefish found in the vicinity of Cebu, Philippines. Like all anemonefishes it forms a symbiotic mutualism with sea anemones and is unaffected by the stinging tentacles of the host anemone. It is a sequential hermaphrodite with a strict dominance hierarchy.
A. thielli has reddish orange body, with a single white head bar that may be connected at the top with a bonnet and two saddles on the dorsal fin and tail base. They have 10-11 dorsal spines, 2 anal spines, 16 dorsal soft rays and 14 anal soft rays. They reach a maximum length of.mw-parser-output.frac{white-space:nowrap}.mw-parser-output.frac.num,.mw-parser-output.frac.den{font-size:80%;line-height:0;vertical-align:super}.mw-parser-output.frac.den{vertical-align:sub}.mw-parser-output.sr-only{border:0;clip:rect(0,0,0,0);clip-path:polygon(0px 0px,0px 0px,0px 0px);height:1px;margin:-1px;overflow:hidden;padding:0;position:absolute;width:1px}6.5 cm (2+1⁄2 in). The species was described from two aquarium dealer specimens.
If A. thiellei is a hybrid, it may show a variety of intermediate colors and patterns similar to A. leucokranosis. Some species of anemonefish, such as A. clarkii show melanism when hosted by S. mertensii however the small number of observations of A. thiellei make no reference to any such melanism.
A. thielli is believed to have originated in the vicinity of Cebu, Philippines.. Field records are lacking for A. thiellei however the most probable hosts are thought to be:
