fry frustration

I had a swordtail that was pregnant so in the breeding bowl she went, when I saw she was going to give birth. She started having babies and I noticed oh the breeding bowl is to small, so I bought a much bigger one but when I got home I noticed of the fry had gotten out, so I checked the lid and it was on tight and no where else was a hole for them to fit through. So I put them in a bigger one and added special grass for them to hide in and then I checked for holes and that the lid was on tight and the divider between mom and baby secure. The next morning all the fry were out in the tank and the mollys got them before I could catch:'( them. Now one of my guppys are pregnant and I was wondering would the newborn fry be able to get through the holes of the breeding net??

 

The mom probably ate the babies

 

but I have seen of them loose in the tank

 

ok ive decided to try make a breeding net, if I take a a plastic container and cut out the the sides that its basically just a outline of the bowl and then take a stoking and put it over the frame of the bowl will the fry be fine in there?

 

Good morning,

Many years ago when I had guppies, platies, and other live bearers, I use something similar to the breeder trap below:

I have 2 different ones of those and even if the lids and everything is on tight the fry get out, I'm am at a loss for ideas atm
