My Black Mollies are very prolific. In the past a member of the club took some off my hands. I have close to 40 in my tank at the moment. Some are only a few weeks old and there are plenty that are bigger but haven't reached their full size. There are also a few that are fully grown. If you have a way of coming to Capitol Hill and a container to move them, they are free. I can give away almost any number between 1 and 20. Maybe even more.
