Randall's Shrimp Goby
The showiest of the commonly available shrimp gobies — a pale body crossed by orange bars, carrying an oversized sail-like first dorsal fin marked with a dark eyespot that it flicks up as a signal. Like the other Amblyeleotris it lives in a burrow excavated and maintained by a pistol shrimp, keeping one antenna's contact with the shrimp while it watches the entrance, and it settles in far better when it has that partner and a soft sand bed several centimetres deep. It stays near the bottom and does not chase food in the water column, so target-feed frozen mysis and enriched brine toward its territory rather than relying on what drifts past. It ignores corals and ornamental shrimp, and its only real risks are being outcompeted at feeding time and jumping, so use a lid.
