Yellowhead (Pearly) Jawfish
The Caribbean Yellowhead Jawfish (Opistognathus aurifrons), also known as the Pearly Jawfish, is a fascinating and charismatic addition to large saltwater aquariums. Known for its pearly-white body, bright yellow head, and constant hovering behavior near its burrow, this species adds both charm and activity to your tank.
Native to Caribbean sandy flats and rubble areas, Yellowhead Jawfish appreciate a deep sand bed for digging and constructing burrows, along with scattered rock for shelter. They are generally peaceful and can be kept with other non-aggressive fish, but they may retreat quickly if startled.
This species is hardy and adapts well to captivity, readily accepting a carnivorous diet of meaty frozen foods.

The Yellowhead Jawfish is a delightful addition to my saltwater tank. It spends most of its time hovering near the sand, which adds a lot of visual interest. I provided a deep sand bed and some rocks for shelter, and it has built a small burrow. It’s peaceful and doesn’t bother other fish. Feeds well on frozen shrimp and krill.

I was initially worried about it being too active, but it’s actually quite calm. It likes to stay near the sand and only moves when it senses something. I’ve been feeding it frozen meaty foods daily, and it’s thriving. The pearly white body and yellow head are very striking.

This fish has become a highlight in my tank. It digs in the sand and stays near its burrow, which is both entertaining and calming. I didn’t have to adjust water parameters, and it adapted quickly. Very easy to care for once the environment is set up properly.
