I changed my tank over to sand yesterday. And lastnight I noticed that some of my fish were swimming right on top of the sand almost as they were dragging their bellies on it. Is this normal or just weird.
I don't know a whole lot about these fish, but I do know that my father-in-law's Dempsey skirts the bottom as he swims the length of the tank. Hopefully someone else will chime in who has a bit more knowledge than myself.
