I have purchased quite a few fish from Petsmart over the years. Usually, I have decent luck with them living over 24 hours once I get them home. The last group I bought were Mollies. I got the Dalmatian Mollies and one of the females I got happened to be pregnant. After about 2 weeks of having them, the pregnant one gave birth.There must've been over 40-50 small fry born, but I was only able to save 14 of them. The babies ended up dying all except for two. They are still alive and doing well in my tank!
