Congrats Coco. I love to watch a new fry drop in any of my tanks. If the fry are growing well, they will soon be too big for any of the other fish to really notice them. Mollies do not have the largest of fry but they are much larger than swordtails, guppies or platies so they are fairly safe right from the beginning. My goodeids have fry that are about twice the size of even molly fry but I never try to keep them in a community tank so I don't know how they would do there. In a tank with just their own kind, I get almost 100% survival. A newborn goodeid that is under about 2 cm is the runt of the litter.
