swordtails as freeders?

[icherno7]

does anyone know if they have any nutritional value to other fish
how about other livebreeding minimal care fish like platies, guppies, mollies?

Swordtails aren't much different from platies and mollies and their care is pretty much the same. I think they interbreed. The nutritional value if used as feeders would be mainly based on how you feed them before giving them to the bigger fish.
