Natural History: The Bluespotted Jawfish is found in large colonies in rocky areas with sand. It builds burrows by digging sand with its mouth. It is observed to close its burrow entrance at night and then reopen it by day. Individuals within colonies are generally separated by 1 to 3 meters. This species is observed to open its jaws when frightened, apparently with the intention of making itself appear large to thwart potential predators.
Husbandry: It will likely be aggressive only with individuals of its own species. This species is notorious for jumping out of uncovered aquaria.
Reproduction: The male courtship display consists of vertical swimming and hovering for several seconds with fins erect followed by retreat into the burrow.
