The dalmation molly fry are fairly easy to care for. just make sure they are in warm clean water, and as said they can eat the same flake food you would feed an adult just make sure you crush up finely. remember, they have small little mouths. :) I don't have much experiance with baby bettas but I suspect they are much the same. clean warm water and food small enough to fit in their mouth. However, i believe there will be other members chipping in with good tips
happy owner of a wild type GFP axolotl named Percival and too many guppies to count.
