Ok I have 2 tanks. I have a 56 gallon tank that is the families and a 10 gallon tank which is mine personally. In the 56 gallon tank we had multiple fish but we did have 2 balloon belly mollies. We noticed one was getting very fat or Murphy was her name at the time. On July 15th of 2009 she had 21 babies but in a separate tank because we supposed she was prego. So of course we changed her name to Murphet. So currently we have 12 of the babies. In my 10 gallon tank I have 6 babies. There is 1 boy and 5 girls. I have a couple questions. Well the male has been chasing the females around lately why? Then also what is he doing when he flares his fins up big. Then when will I know that one of my females is pregnant? Or will I see them mating or how young can they be to have babies? Please help because I just want my fishys to be happy and healthy!:-D:-D:-D
