Comments:I have one female knight goby in a freshwater,10 gallon tank with some zebra danio and some othe fish.Mine isn't that shy.She never hides from me and is always swimming around the tank.The petstore didn't have any males so I couldn't get one.She is always around the corydoras because she thinks she is one.She hovers in one place for a while and then darts to another.She never bothers the other fish and they don't bother her.
