Common name: Jawfish

Opistognathus, commonly known as Jawfish, are a genus of small, burrowing fish known for their distinctive large mouths and behavior of constructing burrows in sandy substrates. They are popular in the reefkeeping hobby for their unique personalities and interesting behaviors. Jawfish are generally peaceful and can be kept with other non-aggressive tank mates. They require a tank with a thick sand bed to accommodate their burrowing habits and are known to jump, so a covered aquarium is recommended. These fish are also mouthbrooders, carrying their eggs in their mouths until they hatch.
