Baby Fish (Fry) First Foods: What to Feed Newborns

Fry mouths are tiny and metabolism is sky-high. Match food size to mouth size and feed often — here’s the progression that raises survivors.

Fry die from starvation and dirty water more than predation — small frequent care beats elaborate gadgets.

Breeding starts with healthy stock and species matched to your water — guppies and corydoras teach fundamentals cheaply.

Vinegar eels survive days in freshwater without drowning fry tanks in acid — perfect for species too small for microworms at hatch.

Microworms wriggle indefinitely in water, triggering feeding responses in fry — one of the easiest live foods to maintain on a kitchen counter.

Infusoria are the invisible first meal for the tiniest fry — easy to culture at home with lettuce, hay, or commercial starters.
