Gobies

Gobies are small, bottom-dwelling fish known for their fascinating behaviors and wide variety of species, making them an intriguing choice for freshwater and brackish aquariums. They are often recognized by their fused pelvic fins, which form a suction cup that allows them to cling to surfaces in the tank. Gobies thrive in well-structured environments with plenty of hiding spots, such as rocks, driftwood, and caves. While some gobies can be territorial, they are generally peaceful and can coexist with other non-aggressive tank mates. Their unique appearance and interesting behaviors, like sand-sifting or perching, make them a favorite among aquarists looking to add diversity to their tanks.
