Randall's Prawn Goby (Amblyeleotris randalli) is a slender, sand-dwelling goby with a pale white body crossed by a series of orange bars and a tall, sail-like first dorsal fin marked with a dark spot. That elongated fin is raised as a signal flag when the fish perches at the mouth of its burrow, making this one of the more visually striking members of the genus. The species occurs across the Indo-Pacific, with records from Indonesia and the western Pacific through the Philippines, Micronesia, Australia, the Maldives, and the Red Sea. Adults reach roughly 4 inches.

In the wild, this goby occupies sand and rubble flats adjacent to reef slopes and drop-offs, sheltering in burrows that are frequently excavated and maintained by pistol shrimp. Adult housing should begin at 30 gallons and emphasize open substrate over dense rockwork. A deep bed of sand mixed with shell fragments and small coral rubble allows proper digging, and the burrow itself needs enough room to exceed the length of the fish by at least an inch and a half. Rock arranged to leave protected cavities at the sand line gives additional shelter options.

Ample hiding places matter, since specimens kept in bare tanks without cover tend to remain stressed and reclusive. Open sand for perching and short darting movements should be balanced against secure retreats. A tight-fitting lid is not optional; this species jumps readily, particularly when startled or when establishing territory. Avoid combining it with other dedicated sand-digging fish, such as burrowing wrasses, unless the footprint is generous enough that burrow sites do not overlap.
