Many different kinds

Worms are are unparelled in conditioning fish for breeding. There are many types that can be cultured, from ones small enough to feed fry to ones far too large for all but full grown monster killies.

The best food for fry

Most, nearly all, killies can take freshly hatched brine shrimp after hatching, but a few require infusioria, which, fortunalty, is very easy to culture.

A long time favorite

There are a half dozen species of daphnia that are cultured. Some people find they very easy to culture while they give others fits.

Instead of BBS

Rotifers are bigger than Paramecium but are cultured the same way and are a wondefull substitute for the ever costier staple baby brine shrimp.

Similar to daphnia

Culture of Moina is the same as Daphnia, but there are a few advantages to Moina.

Wingless fruit flies

It can possibly be argued that worms and flies constitute a near perfect diet for most killifish and neither are hard to raise.

Feshly hatched brine shrimp

WHen brine shrimp eggs are hatched and fed within four hours your fish enjoy the nutrients intended to keep the baby shrimp alive - the yolk sac. There is no better food for fry, but freshly hatched means freshly hatched.
