An amusing fish who spends all day poking its head out of its burrow and opening its wide mouth at any passing fish in an attempt to keep them away. Must have a deep substrate in order to build its burrow, without one it likely will die from stress. Can live alone but do very well in groups. As with all Jawfish, a peaceful tank is usually essential for the chance of survival. |

The Dusky Jawfish (Opistognathus whitehurstii) belongs to the family named Opistognathidae. Typically reaching a max size of about 4.0 inches in length, the Dusky Jawfish is generally passive in nature and moderately hardy in stamina. It's more active during the daytime and less at night, and will hang out or do best in the substrate. According to FishDB current data, captive breeding success is unreported and there are no external signs of sexual differences. Opistognathus whitehurstii should not be housed in a tank less than 20 gallons in size. Tank parameters should be maintained with ph level between 8.1 - 8.3, temperature between 77 - 79 degrees fahrenheit, and a salinity between 1.020 - 1.023. Some of the environmental concerns that you should strive to replicate in your home aquaria to promote succesful acclimation include plenty of hiding places, a mixed substrate, a deep substrate, keep 3 or more, and a peaceful environment.
