The Bristle Tailed Filefish has mottled brown or tan colouring, blending with olive green. This helps the fish camouflage itself and blend into the algae that surrounds its’ natural environment. It is capable of changing shades depending on environment or stress levels. The body is a flat oval shape, with a long dorsal fin and single horn on its’ head.

You can tell males and females apart by patches of bristles on the males’ body or tail. Males are also larger than females. Female Bristle Tailed Filefish lay eggs at the bottom of the ocean, on substrate or around patches of algae. The female will defend the breeding site from other fish.

Bristle Tailed Filefish are usually quite shy and peaceful; but can be aggressive to similar species or family members. They search for food by swimming around coral and rock formations and amongst seagrass.

They are native to East Indian Ocean & Central/West Pacific, including Indonesia, Japan, and Australia
