Common name: Gold-specs jawfish

General information

Randall's Jawfish, scientifically known as Opistognathus randalli, is a captivating species admired for its intriguing behavior and striking appearance. This species is a member of the jawfish family, characterized by their large mouths and burrowing habits. The yellow head and blue to purple body make it a visually appealing addition to any reef aquarium.

Care

Caring for Randall's Jawfish requires an aquarium with a thick sand bed and ample rockwork to provide both the necessary substrate for burrowing and hiding places. They are generally peaceful but can be territorial towards their own kind. It's important to provide a diet of meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood.

Reproduction

In the wild, Randall's Jawfish are known for their unique reproductive behavior where males brood eggs in their mouths until they hatch. This mouthbrooding is rarely observed in home aquariums, but with optimal conditions, it is possible to witness this fascinating aspect of their life cycle.

Habitat

Randall's Jawfish are found in the Western Pacific, in sandy areas adjacent to reefs. They construct burrows in the substrate where they spend a significant amount of time, often with only their heads protruding as they watch for predators and prey.
