Just a thoght, before I switched from tropicals to cichlids I had lt of pregnant fish (swordtails, guppies, mollies, you name it). I successfully bred a twin-bar Platy, a cremecicle Lyretail Molly, a velvet wag swordtail twice, and about 7 guppies. I had one guppy that was very pregnant but couldn't push out those babies, and sadly died, still pregnant. So please feed her food like collards or something like that, boiled, to get her the energy she needs to birth. I had to preform a surgery on one of my guppies and miraculously saved about 3 babies.
