Blue Spotted Jawfish

About this fish

Blue Spotted Jawfish (Opistognathus rosenblatti) are saltwater gobies that do best in aquariums where they can dig and maintain a burrow. In a home reef or community setup, they add natural, engaging behavior as they hover near their burrow entrance and quickly retreat when startled. This makes them a useful choice if you want an active sand-dwelling fish and you can provide the right substrate and security.

Features:

• Jawfish dig and live in burrows, often hovering above the entrance
• They tend to be peaceful and can be kept as reef safe in appropriate community tanks
• A deep sand bed with mixed grain sizes and some rubble supports stable burrow building
• They will dart back inside when startled, making an escape-resistant setup important
• Offer a diet of frozen mysis and brine shrimp for regular feeding
• Give new arrivals a quiet spot and acclimate them slowly so they can settle in
