I have 4 Balloon Mollies (3 female, 1 male...siblings) who were born in my granddaughter's tank. They have since moved to another state so we moved her tank to my house. I now have them in one of my 20 gallon community tanks. Have never seen fry even when in her tank. I know they could very well have been born and eaten quickly. Always had lots of floating Anacharis in both tanks just in case. Very little floating now although the tank they are in is planted. I really don't need more fish as all my tanks are stocked but if I see fry, they are going into protective basket and I'll decide what to do with them later. LOL. My question is...one of them looks squared off. All but male are FAT of course! LOL Does this mean she will give birth soon? I don't want to stress her by putting her in basket too soon. These are not beautiful, colorful fish but are very friendly fish and I have an emotional attachment to them because of their history. Any help?
