Well, even though I didn't want mine I didn't have the heart to let them all be eaten. I did scoop them out and stick them in a small bowl with an air stone at first. They were so small I didn't use a filter at first and I just had to be very very careful when trying to clean their bowl with my turkey baster that I did not suck them up.
Actually, I did suck them up on purpose with the turkey baster at first to get them out of the tank with their mom and my betta Cornelius because he was trying to eat them and I felt sorry for them. I did that and also tried to make catch them with little plastic cups.
All you can do is either stick plants like anacharis or . . is hornwort or camboba that has fry-friendly shapes? I think so. I also put very tiny decorations with hidey holes that no other fish could get to in the tank with the pregnant mom. She has had 3 sets of fry already and she's still totally fat so I know it will happen again. (Jeez!)
Um. . . not sure what else your questions are? I went on a tangent so maybe I didn't help at all!
Also I do have 2 decorations that scream "fry can hide in here". I had 2 pretty Bioorb decorations that didn't seem right for betta but very good for fry to hide in. I have these but you could get something similar instead:
Your thread title is really funny, btw.
I think the airstone at least made sure there was oxygen in the bowl, and I bought hikari first bites to feed them.
