This is one of a few poisonous gobies!
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. Ref: https://www.fishbase.se/summary/Acentrogobius_nebulosus.html
