Blue Spotted Jawfish
Opistognathus rosenblatti
The Blue Spotted Jawfish originates from the Eastern Pacific. The Blue Spotted Jawfish head is normally yellow tapering down to blue over the tail. This Jawfish is covered in blue spots and streaks. Excellent choice for small reef tanks. Jawfish seem to have distinct individual personalities. Normally peaceful to other reef inhabitants but should be kept singly as they are aggressive to their own kind. Jawfish spend much of their time hanging around the rock work, specifically in their burrow. They need 2 to 4 inches of sand to dig their burrow into and will occasionally remove so much sand that the base rock begins to shift. Therefore, it makes best sense to setup your reef tank with the base rock placed on the bare bottom of the tank as opposed to sitting on the top of the sand. One other note, Jawfish have a tendency to jump, especially at night. They seem to have a fondness for jumping into hang on filters or refugiums.
