Mandarin fish are are tropical, marine fish found in warm water that can be be seen in much of the western Pacific including the Philippines, Indonesia, Hong Kong, Australia, and New Guinea.

They have a broad, depressed head and are primarily blue with orange, red, and yellow wavy lines. Mandarin fish are small, reaching a maximum length of 6 cm (or 2,36 inch).

The vibrant colors of this species indicate to other animals that it is dangerous to consume. To make up for the lack of protective scales, the mandarin fish’s body produces an odorous, foul-tasting, toxic mucus.

Mandarin fish are reef dwellers, preferring sheltered lagoons and inshore reefs. While they are slow-moving and fairly common within their range, they are not easily seen due to their bottom-feeding habit and their small size. They feed primarily on small crustaceans and other invertebrates.
