I'm also worried about mine. My molly is super pregnant and hasn't dropped fry for a couple of months. She is enormous. I've actually placed her in a 10gal hospital tank with 1 tsp pure epsom salt per gallon - with a male molly who was pineconing and he is 100% better after a week and a half. She's been in there for 5 days. I was getting worried about her because she was getting a white lump at the end of her tail but the start of her tail fin. She's gotten a lot better but still won't have her babies.
