notes
   A rare find usually, but a gorgeous one. The problem is it usually commands a pretty high price. Must have a deep substrate in order to build its burrow, without one it likely will die from stress. This particular species need to be kept singly unless a male/female pair are acquired. As with all Jawfish, a peaceful tank is usually essential for the chance of survival.   
overview
  
The Bluespotted Jawfish (Opistognathus rosenblatti) belongs to the family named Opistognathidae. Typically reaching a max size of about 4.0 inches in length, the Bluespotted 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 rosenblatti 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, and a peaceful environment.

     Amongst all the Jawfish family, the Blue Spot is perhaps the the most stunning. Mine seemed very difficult to get aclaimated from the start. Hid 95% of the time. Unfortunately, he did not survive. Even with the best preperations and pristine water quality, sometimes we fail. It simply may of been that particular fish. Being able to observe a particular fish for several days, or longer, prior to purchasing is the best way to judge a fishes health and suitabillity for your tank.
