Tank compatibility[edit]

This fish is reef-safe and should be kept with similar-sized peaceful reef-dwelling fish. It is peaceful towards tank mates but is highly territorial towards its own species. Keep only one Jawfish to a tank unless you have a mated pair.

Environment specifics[edit]

There must be a reasonable amount of substrate for this fish, either sand or small gravel, as this is a burrowing fish. A tight fitting lid is a must as this fish is also an excellent escape artist!


A striking little fish, the Blue-Spotted Jawfish's body is orange-yellow in colour, lighter around the head and darker towards the caudal fin, with large iridescent irregular blue spots covering the body and head, on the head they are small and towards the caudal fin they can merge into horizontal bands. The dorsal and caudal fins are yellow in colour. It is typical Jawfish in shape with a blunt head and large eyes with an elongated slender body.
