I have two red eareds I got from some people who were mistreating them, I bought them a new tank and filter (which they didn't have at all before) UV lights and set them up. For a while they were fine but now one chases the other all over the place biting it. I believe they are both males, both about 5 inches. Is there anything I can do to stop them fighting besides splitting them up? cause I don't have space or money for another set-up
