Haha. I do not like being bit. No, it doesn't hurt, but it scares me and makes me jump. And yes, the fish could end up on the floor (which is what happened to mine all those years ago, though she was fine). I know that my female would probably bite me if she was given the chance. However, my boys actually seem calmer and less likely to do so. Not that I will ever give them the chance!
Remember that the tank your fish lives in is his or her's whole world. Ask yourself this question, and answer it honestly: would you choose to live there?
