Live food for killies - worms
Types of Worms encountered in aquaria: most are Fish Food

Worms have long been understood to be an integral part of many - tropical fish's diet. While most killifish eat ants that fall from trees a few eat primarily aquatic crustaceans and worms instead, for example the Diopteron subgenus in Aphyosemion. But worms will put all killies in top condition for breeding and it's no wonder aquarium books suggest "condition for breeding by feeding worms". It really does work, nothing else seems to work as well. Fortunately they're very easy to culture, clean and disease, alage and pest free.


Panagrellus nepenthicola (Nemtode)

Banana worms are a close relative to the beer mat worm or microworm. They both eat yeast and can be cultured with a bit of yeast on some oatmeal.


Lumbriculus variegatus (Annelid)

Blackworms replaced the Tubifex worms in the late 20th century. Two producers of California Blackworms exist that supply all of North America. They're not cultured in the sense microworms are but are instead bred in huge ponds.


Eisenia fetida (Annelid)

The best known are African red worms, commonly sold as bait, make an excellent food for larger fish. African nightcrawlers can also be grown but are really too large for anything but large gluttonous fish.


Enchytraeus buchholzi (Annelids)

Rather small, barely an inch long grindals have a little less fat that white worms and are easy to culture. They like room temperaure (70 - 80).


Panagrellus redivivus (Nematode)

Perhaps one of the easiest and most foolproof foods to grow, microworms are, as the name implies, very small, and are used for feeding fry.


Turbatrix aceti (Nematode)

They aren't eels, of course, but an aquatic version of microworms. Again - very simple to grow.

Walter Worms

Panagrellus silusioides (Nematode)

Walter worms are almost exactly the same as microworms except they tend to remain active in the water column a little longer. Unless you're caring for bottom feeding fry they may be a better choice than microworms.

Enchytraeus albidus (Annelid)

The next size up from Grindal worms they are also easy to culture. The secret is, they prefer it cool (50 - 65). Given soil, a cool environment and regular feeding, they are fairly prolific.
