As the common name suggests, the middle bar is very wide, about twice the average width of other anemonefishes and is shaped like a flat-topped pyramid.

The dorsal fin may be orange or yellow[2] The broad midbody bar is distinctive, and A. latezonatus is unlikely to be confused with any other anemonefish.

[9] Anemonefish and their host anemones are found on coral reefs and face similar environmental issues.

Like corals, anemone's contain intracellular endosymbionts, zooxanthellae, and can suffer from bleaching due to triggers such as increased water temperature or acidification.

The finding of A. latezonatus being hosted by two additional sea anemone species [9] may reduce the risk of extinction associated with specialisation.
