Description
The Rock Goby is a temperate marine fish known for its mottled brown and black camouflage, allowing it to blend seamlessly with rocky substrates. It is a bottom-dwelling species that often perches on rocks or hides in crevices. While generally peaceful towards other species, it can be territorial with conspecifics, especially in smaller tanks.
