This goby digs tunnels near and underneath rocks. Because of this you need to make sure that your rock work is secure so that you don’t have an avalanche in the tank. They can be kept with just rock and PVC pipes but they do better with sand. Juveniles have straight lines on their bodies; as they get older they develop a snakeskin-type pattern. They do get very large, reaching 18 – 24 inches in length. Can be kept in small groups without any problems. Juveniles tend to stay together but as they reach adult size they separate somewhat.
