Could underfeeding swordtails result in fry not surviving?

A thought just came to mind. I have 5 swordtails, one male 4 female. The females keep getting pregnant but so far only one fry has made it to juvenile stage. I saw one other fry for a few days then he disappeared. My question is could the loss be due to my underfeeding them causing them to aggressively go after the newborns? I have 2 good-sized clumps of java moss for them to hide in so I would expect more than one in 3-4 months. I'm thinking of getting either some guppy grass or a breeding box. Thoughts? It's a swordtail only tank at the moment..

Do you target feed the fry?

I mean sure if a fish is hungry itís going to go after itís own young vigorously. How often are the females dropping young? For sure big wads of guppy grass etc will increase their chances of survival.

Yes, Plus swords will eat their fry if they can catch them adding more hiding spots can help.

Something like this is perfect once you block up the ends with some filter sponge.

In my experience swordtails and platys aggressively go after their fry no matter what. Feeding well may help but they still have that prey instinct. Guppies and mollies are less likely to eat them. Mollies in particular in all my years of keeping them I never witnessed them eating fry.

Newborn fry usually head right to the surface. More fry would survive with a thick growth of floating water sprite to hide in.

I've decided to move some of my java moss. I had an overgrown clump on a piece of driftwood I trimmed a large amount off it and moved it to the other end of the tank on top of the other java moss clump, so now it reaches almost to the water top. I also have a piece of cholla wood, so I might try HairyNoseWombat"s idea.
