Ive had my swordtail fry for coming up a month now and they are still very small, one of my mollies had some fry about 5 days ago and they are already much bigger... is this usual??!
Okay, well, if they are a month old, they should probably be off Liquifry. I'd go over to fry food, and crushed up flakes now. Maybe some live BBS, if you can get it?
Also, how many fry do you have in the breeder box? That could be really limiting their growth...any other place you could put them? Do you have a small fry tank?
