Blennie, Blennie, Goby compatability

Should be okay--the watchman goby will build a burrow and keep to it, the lawnmower and the scooter will go all over the tank. Keep in mind that scooters are actually dragonettes, and do best in tanks with lots of live rock and pods--make sure it's taking prepared foods as well before purchase. In smaller tanks without lots of live rock, they often starve.
