The round goby is a small, aggressive bottom-dwelling fish. They usually grow three to six inches long, but can grow up to ten inches. The young are solid gray and adults are light grey with dark blotches.
How big do gobies grow?
They can grow to 10 inches as adults. Gobies have large heads, soft bodies, and dorsal fins lacking spines; they slightly resemble large tadpoles. The gobies' unique feature is their fused pelvic (bottom) fins, which form a suctorial disk that aids in anchoring the fish to the substrate.
How fast do gobies grow?
Female round gobies reach sexual maturity in one to two years while males do so in three to four years. Gobies in the Laurentian Great Lakes typically mature up to one year earlier than in their native habitat in Europe.
