I got my pregnant Dalmation Molly which I had in my main tank for around 3 weeks before it gave birth (the only other fish in the tank were two male guppies), and it had 23 fry. The other fish were perfectly fine, but the fry died off the same night that they were born, and I was not sure why. It was a 20 gallon tank, 78F with no chlorinated water or cycling/dealgaeing chemicals added at all, a carbonated pocket filter and a small airstone added.
After owning fish for a few years in that tank, when the Female guppies I bred in the tank had fry, they all survived naturally, but whenever a Molly would have fry they would just die the same night they are born.
I have been thinking instead of letting the Molly breed her fry in a breeder net-box, I was going to separate them into their own tank to make sure that the only bacteria the fry are involved with is their mothers and their own, but I am not sure about if this would work or not.
Is there any specific things I need to have in the tank to insure the survival of the Molly fry? It's sad to see all of the little fry get born, swim into the plants to hide or sit at the bottom of the net, and then a day later be floating around the tank dead.
