I bought my very first fish yesterday, two black mollys. I am figureing out that I should not have gotten mollys for my first fish. I had the two mollys in a 30 gal tank with a large pleco that my sister gave me bc he was having territorial issues in her tank. Anyways, this morning I woke up to babies! The other molly was eating the babies so I separated them as fast as I could into my sons 1.5 gal tank. Now what? I don't mind have a few extra, but I don't want a million mollies. What do I do with them? How do i know if the other is a male?
