The Blue Dot Jawfish, also known as the Bluespotted Jawfish, was first discovered in the Tropical Eastern Pacific in 1991 by Allen and Robertson. This lively fish boasts bright, flamboyant coloration in contrasting shades of yellows, oranges, and blues with iridescent, irregular-shaped blue spots decorating the entire length of the head and body.
The ideal setup for the Blue Dot Jawfish is an established 30 gallon or larger aquarium with plenty of live rock and a layer of fine to moderately sized sand substrate to sift through. Ample horizontal living space and a substrate layer of at least 3″ in depth is necessary for this burrowing fish. In addition, a tight-fitting canopy is necessary to prevent the Blue Dot Jawfish from jumping out of the aquarium. It will rarely become aggressive towards other fish, but is territorial and will fight with its own kind unless they are a mated pair.
The diet of the Blue Dot Jawfish should consist of a variety of marine fish, crustacean flesh, and mysid shrimp. It should be fed at least three times per day.
