Guppies can't eat Molly fry. Too big for their little mouthies. However, the other places are good.
You might also be able to sell a few on here if it comes to that. 
Well my adult ballon mollies are about(------------------). If yours are about that size (people say they get abot 4 inches which i do not believe cause all three of mine are full grown and that big.) that expect the fry to be about (---) including fins. Much like the size of a guppy fry. At least mine were.Annastasia said:Molly fry are bigger then most other Livebearer fry. Maybe [----] that big, or slightly larger.How big will the fry be?

So either I raise them if I feel like it or my bettas get a nice snack
Last week I bought a pair of jewel cichlids and you should see those guys eat fry. I could not believe how big their mouth get and how good of hunters they are. It's good to feed cichlids and bettas live food sometimes. They love the chase and I read it's nutritious for them especially if you feed the fry a big meal before you feed them to the other fish.
Jeez. Well, Leo, my betta buddy, you shall be feasting in a few days....Nope they are safe as can beaquagirl said:They can't eat them already?Jeez. Well, Leo, my betta buddy, you shall be feasting in a few days....
When mine are born they swim about with no worries in the world
