Black Cap Jawfish - Opistognathus lonchurus

The Black Cap Jawfish typically reside in burrows that they construct in sandy substrate. They will stuff their mouth with sand and spit it out elsewhere, slowly creating a tunnel. Utilizing the protection of these burrows, these fish will hover feeding on plankton or other small organisms, ready to dart back in at the first sign of danger. They are territorial of the area around their burrows.

The Black Cap Jawfish are mouthbrooders meaning that their eggs hatch in their mouths, where the new-born fry are able to be protected from predators. The Black Cap Jawfish is ideal for a reef aquarium, although, it may eat small, delicate shrimps. It requires a tank with a sand and coral rubble substrate of about 5 inches deep for burrowing. The sand should be of various particle sizes and various sized rocks among the soft substrate will help to reinforce the burrows against them.

The Black Cap Jawfish is a fascinating fish to watch, as it will spit sand at anything that comes to close to its burrow. The Black Cap Jawfish should be housed with other peaceful species and small groups can be kept if the tank is large enough. The Black Cap Jawfish will often spawn in captivity and the male will incubate the eggs in its mouth.
