Who Gives A Fish Forums

If you're culturing microworms, keep the culture in a warm spot. They reproduce faster that way, and you'll always have food ready for the fry.

Also, keep an eye on the fry's bellies. If they're nice and round after feeding, you're on the right track. If not, you might need to adjust the food size or type.

Yep, that's the trick. Full bellies mean happy fry. Just don't let the food sit too long or it'll foul the water.
