She drops every 6 weeks like clockwork. It is a simple case of feeding her a balanced diet of everything in my fish room with nothing left out. I do emphasize the spirulina flake in her diet because it is a definite plus with any molly. She lives at about 75F, 24C, in a pH of 7.8 and some significantly hard water that never reads less than 12 degrees of hardness but often reads higher. She produces absolutely no fry that I ever find in my community tank no matter how long I leave her because the community tank means lots of predators to clean out all the fry. The only fry I have ever seen survive in that tank was a single platy after over a year of platies and mollies both breeding constantly in the tank. The way to get survivors frequently is to use a birth tank that has enough room to house the female in comfort so you are not trying to move her at the last minute. I find that if she is well fed, the fry survive with almost no effort on my part except to feed them and do water changes.
