It hovers vertically above a burrow it digs and maintains in the sand bed, darting back down tail-first at the first sign of trouble.

The jawfish digs a vertical burrow and lines the entrance, so depth and a few building materials matter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre they reef safe?\u003c\/strong\u003e\u003cbr\u003e\nYes.
