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.

[2] This strict sized based dominance hierarchy makes the relative size of the parent species critical in shaping the outcome of hybridization[8] In this regard A. chrysopterus is one of the largest anemonefish, growing to 17 cm in length.

[8] The distribution of A. sandaracinos and A. ocellaris largely overlap from northern Australia through the central Malay Archipelago to the Philippines.

Possible parent species If A. thiellei is a hybrid, it may show a variety of intermediate colors and patterns similar to A. leucokranosis.

A. perideraion has a pinkish body and a continuous white stripe along the base of the dorsal fin, rather than broken into a bonnet and two saddles.
