Cream and butter-yellow bars run the length of its body, dusted with coral-pink spots and tiny white pearls, and it spends the day propped up on its pectoral fins at the mouth of a burrow it dug itself. Like the other \u003cem\u003eCryptocentrus\u003c\/em\u003e shrimp gobies, it can form a genuine partnership with a pistol shrimp: the nearly blind shrimp does the digging, the sharp-eyed goby stands watch, and both share the tunnel.

Drop some sinking food near where you last saw it and it will start appearing more each day.
