Jawfish are well known for frightening easily and will jump out of uncovered aquariums. The Yellowhead Jawfish is moderately hardy. It tends to be shy and is best kept with other docile fish. This fish will spend much of its time in its burrow and when it does venture out, if it is startled, it will bolt back into its burrow tail first with lightning speed. Known for being a jumper when startled or frightened, the tank should have a tight-fitting lid.
