Hi Fixer,
Nothing wrong with that. Do you have Moon fish in your tank. I like those very much. I also like the fish that breed the little ones in their mouth. Fish are operating on all sorts of planes, there is ground fish, the surface fish. When I was young we had little sticklebacks in a jar and saw how frogs developed. If you like fish, you are a nice person.
have a nice day,
polonus
