The Pearly Jawfish is commonly referred to as the Yellowhead Jawfish or Yellow-headed Pearly Jawfish. It features a yellow head with light blue-green body, which adds a beautiful splash of color into the tank. The Pearly Jawfish grows up to 4-5 inches in the aquarium, and overall it is a cute fish with a great personality. It is moderately hardy and is best to keep along with docile fishes, since it is shy in nature. But if it is kept in a moderate aquarium, the Pearly Jawfish can be kept along with other fishes also. Since it spends much of its time in its burrow, the aquarium should contain 5-7 inches of fine soft substrate. It looks lovely when the Pearly Jawfish dances up and down in the burrow. It is known to be a good jumper so it should be kept in a covered aquarium. Since it is a mouth breeder, the male Pearly Jawfish will hold the eggs in his mouth. It is typically a shy feeder and should be enticed with small pieces of mussel, daphnia, brine sgrimp, bloodworms, or other meaty foods. We recommend you to feed them near the burrow, since the Pearly Jawfish is a quiet fish. It should be kept in a tank greater than 10 gallons and thrives well in a temperature range of 72-82 degrees Fahrenheit. The Pearly Jawfish doesn?t bother other tank inhabitants and that is why it is considered reef compatible fish.
