The '''blue-spotted jawfish''' (''Opistognathus rosenblatti'') is a [[species]] of [[jawfish]] native to the [[Gulf of California]]. It is an inhabitant of [[reefs]] where it is found in large colonies at depths of around {{convert|12|m|ft}}. This species hides in its burrow at night, completely sealing the entrance. Every morning, it rebuilds the burrow entrance. It can reach a length of {{convert|10|cm|in}} [[fish measurement|TL]]. It can also be found in the [[aquarium]] trade.<ref name
The blue-spotted jawfish was first discovered in the Tropical Eastern Pacific by Gerald Allen and David R. Robertson in 1991.<ref name = tfh/>

==Biology==
Jawfish are named for their large mouths, which allow them to catch food. Their large mouths also allow them to dig their burrows by taking big mouthfuls of sand and spitting them out in order to create their hideaways.<ref name

==Habitat==
The blue-spotted jawfish are very social amongst other members of its own species
▲The blue-spotted jawfish are very social amongst other members of its own species, they are not aggressive except to those who try to enter their burrows. They are found in cold water at deeper depth of the ocean in sandy rubbles and reef areas. They live in colonies of up to several hundred fish with a minimal spacing of 1m to 3 m between individuals. They cover their burrow entrance at dusk and rebuilt the opening every morning. Unlike the ''Opistognathus aurifrons'', the blue-spotted jawfish only spend time out and above their burrows during warm summer season.<ref name = tfh/>
==Health==
Edit: Brookynella is easily treated in a quarantine tank using malachite green in combination with formalin.
▲The blue-spotted jawfish have small scales but they do not carry parasitic infestations and infectious disease as the other fish family with small scales.<ref name = tfh/> They are two diseases that can affect the blue-spotted jawfish. First of all, the brooklynella and blue spotted jawfish disease.<ref name = aquanerd>{{cite web | url =http://aquanerd.com/2009/09/better-left-in-ocean-blue-spot-jawfish.html | title = Better Left in the Ocean – Blue Spot Jawfish | accessdate = 25 October 2018 | publisher = AquaNerd}}</ref> When the blue spotted jawfish are affected by the brooklynella, it is likely that they will deteriorate and die within approximately 24 hours. The symptoms of brooklynella include: peeling skin and color loss all over the body, no appetite. They may leave their burrow and list around until they eventually die.
The so-called "Blue spot jawfish disease" is almost always damage to the fish caused by; rough handling, coarse or abrasive substrate, being kept on bare glass, or, from being kept at above 21c.
==Reproduction==
Jawfish are mouth brooders, they utilize their mouth to hold the eggs until they reach the hatching point. They incubate the eggs in their mouths for about 5 to 7 days. In addition, males display behaviorally and color
▲Jawfish are mouth brooders, they utilize their mouth to hold the eggs until they reach the hatching point. They incubate the eggs in their mouths for about 5 to 7 days. In addition, males display behaviorally and color wise in the summer months by becoming bright white, dashing 3 to 4 feet above their burrow trying to attract the females. If the male is successful attracting the female, the female join his tube for a few minutes after returning in hers.<ref name = tfh/>
