Opistognathus aurifrons, commonly known as the Jawfish, is a captivating marine fish prized for its unique burrowing behaviour and striking appearance. This species is suitable for marine aquarium enthusiasts who can provide the specialised care it requires.
Care Level: Moderate to advanced. Jawfish need stable water conditions and a well-prepared environment to thrive.
Temperament: Generally peaceful but can be territorial towards conspecifics or similar species. Best kept singly or as a mated pair in sufficiently large tanks.
Diet: Carnivorous. Feed a varied diet of meaty foods such as mysis shrimp, brine shrimp, finely chopped seafood, and specialised marine pellets. Feed small amounts 1-2 times daily.
Tank Requirements: A minimum tank size of 120 litres is recommended to provide adequate space for burrowing and territory establishment. A deep sandy substrate (at least 5-7 cm) is essential to allow natural digging behaviour. Provide plenty of live rock or PVC pipes to serve as burrow anchors.
Reef Compatibility: With Caution. While generally reef safe, jawfish may disturb small invertebrates or corals by digging. Avoid keeping with very small or delicate reef inhabitants.
Water Parameters: Maintain stable marine conditions with temperature between 24-27°C, salinity 1.023-1.025 SG, pH 8.1-8.4, and moderate water flow.
Origin: Not Provided.
Maximum Size: Typically grows up to 10 cm in length.
Opistognathus aurifrons is a rewarding species for aquarists willing to meet its environmental and dietary needs. Its intriguing behaviour and striking appearance make it a standout addition to suitably sized marine tanks.
