My 4 month old female platy has looked very pregnant for a few weeks now and I have been watching her closely, hourly, for signs of delivery (squaring off of her belly, etc). Yesterday early evening I found her hiding, unusual for her, and one baby in the tank. She still looked extremely pregnant and her belly slightly squared off so I quickly scooped her up into the breeder but no more babies overnight. She is black in color so I can't see the dark spot in the rear of her belly. I kept her overnight but she seemed so stressed so I released her this morning. I do have the one baby. I caught it in the tank. Do you think the baby was premature? Or she stopped the delivery? Or can they have two stages of pregnancy at one time and maybe she is now working on the next one? Or maybe because this is her 1st pregnancy she only had one? Maybe more were born that I didn't find but she still looks pregnant and squared off. Any advise is appreciated.
