I didn't think it would happen. First of all, I had a f Black Molly, which my f molly kept biting on her so I put her in quarateen, don't know if I spelled it right, couldn't find the spell checker, anyway, I noticed a lot of bites on her and I thought she may make it but she was nose diving then she came belly up and not moving. In the mean time I went to Petco and bought two f black Mollies and evidently one was preggie because I started to see little fries hiding in the rocks a 1/2 hour later. I caught them and put them in the breeder net with some gravel so they can still hide. I counted 17 of them plus 1 dead. I am so thrilled. I had some Guppies but they died off one at a time. Maybe I will get a different, small tank just for Guppies for I like them. Just wanted to share this with all of you.
