The Blue Spotted Jawfish, Opistognathus rosenblatti, also known as the Bluespotted Jawfish, is without question one of the most beautiful goby species available. It has electric-blue striping over a yellow body with an elegant yellow dorsal fin. The slender Blue Spotted Jawfish will move sand from the substrate and dig a burrowing hole to live within. Often times this fish will use a shell as it's door to the hole. Their head will pop out of their hole looking for food and predators. Upon seeing food they will float out of their hole in a standing motion to grab the food and then rush back into their home.Their body has blue spots on top of the orange body and head. They have large eyes giving them an "alien" appearance. More than one can be kept per tank. These fish are also jumpers, so precautions should be taken to secure openings at the top of the aquarium. Gobies compose one of the largest family of fish in the ocean. These small fish live around reefs or on sandy flats. Many of the Gobies are known for their burrowing behavior. These fish use burrows in the sand for safety. Some of the Goby species are known to share their burrows with Pistol Shrimp; behavior that can be duplicated in the home aquarium. Most Gobies have cupped ventral fins that nearly join just below their gill plates that serve as perching mechanisms so the Goby can always be on the lookout in a resting position. The Goby is a tremendous addition to the home aquarium.
By far my favorite fish. I had to empty a display into my qt tank so that it could be qt'd in a tank with sand in it. Awesome colors and awesome personality. Been here a week and no signs of parasite or illness.
I have this goby for about a month now. I was surprised to find how active it is (unlike other gobies). It swims alot during the day. It opens its mouth when it senses danger ie when another fish swims close to it. The negative is the cost but I find this fish a joy to have in my tank.
