I've got a surprise platy fry without any idea about how to take care of it. In the morning when I was feeding them I noticed that the female platy was thinner. So I thought may be it gave birth. I searched and found a single fry which was hiding under a decoration. I was very happy to see a little baby fish. I thought it will survive that way. But the dumb fry again came out and was eaten by the Boss platy. I have separated the next fry. I really want it to survive. I've put the fry in a small disposable coffee cup with some tank water and I've put the mother in a fish net at one corner to protect any other fries in case they are born. So what should I do to make that fry survive? I've tried feeding it by crushing a pellet. But it won't eat. Can I keep it in the cup until it's bigger? I'll be changing the cup water daily. I'm so much excited. I was jumping out of happiness.
