Babies!!! Again...

My mom was here visiting last week. She wanted to get a pregnant black Molly for my kids to see the babies. I didn't think she was very pregnant so I let her out of maternity ward and with the rest of the fish. The next day she looked skinnier than she was the previous day. So we figure she must have had the babies after I let her out and they all got eaten. So a couple days later I got another Molly that we knew was pregnant. My mom had to go home on Saturday and there were still no babies by then. Well, this morning when I checked on the fish and fed them there were still no babies. But about an hour later there were black dots on the bottom of the maternity ward. I had a meeting to go to so I took out what babies she already had and then left. There were no more babies when I got home so a couple hours later I let her out. I counted about 28-30 babies.
