I'm not familiar with platys (I originally thought I had a
Platy but soon learned that is was a molly) so I am unable to advise how you can figure out if it's pregnant or not. My black molly always got huge and it seemed each time she had babies, she was even bigger the next time. I guess this makes sense as I've heard that they have more and more babies as each birth takes place. She gave birth about every 40 days. Her last birth was the first time she layed on the bottom of the tank. She soon died after this last birth, so I don't know if that had anything to do with it or not. :( Anyways, those "eggs with eyes" are not going to hatch...they are fry that didn't make it (or fully form), so they can be removed. I've had that happen everytime my molly has given birth, but there were always plenty that did survive...so you may find a few that live (they will be tiny fish, not eggs) and you'll see them swimming around a little. If this is your platys first birth, you may not have any that survive but you never know. That was how it was with my molly. However, she has had 3-4 births after and have always had plenty survivors. I think my molly only took a couple of hours to have all her babies, so I'm not sure if your
Platy is finished or not. I've read that it could go on for a day or so, but I never noticed that with my molly. I had a
Guppy who also had babies but I never had any unhatched fry (egg looking with eyes) ...any fry that died in the breeder tank were basically "belly up" but fully formed. I hope this helps, as I'm still learning myself, but I believe this follows suit with all the livebearers. :D
