Quakerfish

Found in pairs, hovering in an undulating manner close to their burrows, where they can dive for cover, these burrows are constructed under rocks, rubble, and sandy areas, of seaward reefs.

Tilefish form undersea Pueblo villages made from gravel or sand substrate these self-made burrows and caves are at the base of reefs or piles of rock, often in canyons or at the edge of steep slopes.
If disturbed they quickly dive head-first into their constructed retreats.
