Parva Goby

Found in pairs, or small schools, sometimes sharing their burrows with other large species, around coral heads and sandy areas, over lagoons, sand flats and slopes, of coastal reefs.

These Gobies feed by taking a mouthful of sand that is filtered through the gills for tiny creatures.
They make large homes on sandy areas below rocks, with a small entrance that is covered over at night, when predators are near these Gobies dive into the sand and swim through the sand to escape danger.
