Common name: Goby

Gobius is a genus of small to medium-sized fish commonly known as gobies. These bottom-dwelling fish are characterized by their fused pelvic fins that form a suction cup-like structure, allowing them to adhere to rocks and other surfaces. Gobies are popular in the reefkeeping hobby due to their interesting behaviors and ability to adapt to various microhabitats within the aquarium. They often form symbiotic relationships with invertebrates like pistol shrimp, which adds a dynamic aspect to their care. Gobies are generally peaceful and can be kept with a variety of other marine species.
