Character and suggestions regarding care

A semi-aggressive Jawfish.

Yellowhead Jawfish can grow up to 10 cm what is approximately 3 inches. 1 specimen basically needs at least 1200cm2 of water surface which is approximately 186 square inch. This fish should be kept in aquariums that are medium. (e) Medium aquariums have at least 113 Litres (30 US Gallons). Large aquariums have at least 265 Litres (70 US Gallons). Capacity of very large aquariums is at least 700 Litres (185 US Gallons).

It is easy to keep the Yellowhead Jawfish. (e) The specific gravity (SG) should be between 1,020 and 1,025, the temperature between 23°C (73.4°F) and 26°C (78.8°F). The suggested level of pH (a measure of the acidity/basicity) is between 8.0 and 8.3 which is usual for most marine fish.

Yellowhead Jawfish does not need a large aquarium if it is alone, but it should have a high sand bottom, because it likes to bury into it. If you have more of them in one tank, every fish should have its own territory (about 30 cm2 of sand bottom for one fish), so they will need more place. Then you should have live rocks inside of the aquarium too, however they should not be placed one on one, because these fish can make fall them down.

This is a peaceful fish to it’s own specie, but there might be problems if you put other bottom species into the tank. In such situations they are more aggressive to new fish, so all of the Jawfish should be bought and introduced at the same time, otherwise the new Yellowhead Jawfish can jump out from the tank.

Opistognathus Aurifron is a carnivore so you should offer them meaty food; such as frozen or live brine and mysis shrimps, crushed krill, and other crustaceans.

This fish was bred in tank and it is a mouth-brooder, which means, that this fish protects it’s newborns by keeping them in the mouth.
