Hi, this platy fish had 3 fry around a week or two ago. Once we spotted the fry we moved her into a breeding box and caught the fry so she could still have more without them being eaten. However I think this really stressed her as she stopped giving birth and hasn’t had any more since but still has a black spot on her. I’m confused whether she will still have the fry or if the 3 we found were premature
 
If the 3 babies were swimming around they weren't premature.

She might not be pregnant and could have worms.

It is preferable not to move pregnant fish because you can stress them and even damage the unborn fry. If you have to move pregnant females, carefully catch them in a net and then use a plastic container to scoop the female and net up in some tank water. Move her (in the net in the bucket of water) to a new tank and then carefully pour her into the new tank.

If you moved the female to a smaller aquarium that would stress her.

If you used completely new water in the new tank it would stress her. If you set up a new tank for her you should fill the new tank with water from her current tank, so the water is exactly the same.

If the new tank does not have any plants in it will stress her. Put some plants in with her. Water Sprite (Ceratopteris thalictroides/ cornuta) is the best plant for livebearers. It normally grows on the surface but can also be grown in the substrate where it grows into a lovely light green shrub.

If you don't have any live plants then add a heap of artificial plants to provide her with shelter when she goes into labour, and to give the fry somewhere to hide when they are born.

Make sure the new tank has an established filter in it so the water stays clean.
Do not put the female into a tank with males until at least 1 week after she has given birth otherwise the male/s will stress her out.

Try not to move the female for at least 1 week after she has given birth so she can heal up. If you have to move the female after she has given birth, use the method above for moving pregnant females.

Most female platies do not eat their young if the female is well fed and there are plants in the tank, but will eat them when they are confined to a small breeding trap.

I used a net to catch her and put her in a washed out butter tin which had her tank water in while we caught the fry and then moved her into the breeding box back in the main tank she was in but she hasn’t had any more
