Next week I reculture my microworms. I hate wasting and I have a very good culture going. With minimal care your culture will last you forever!
Some info on microworms:
Microworms are grown in a culture of either oatmeal or cornmeal (I use cornmeal) and feed off yeast. They are actually nemetodes. Microworms are a very good first fry foods. Unfortunately they may cause missing ventrals if overfed so be sure to feed with something else. Anyway they'll keep your babies from starving.
What you'll get:
A microworm starter culture
A copy of Linda Olson's culturing instructions (including microworms, vinegar eels, and baby brine shrimp).
Culture - $10
Instructions - FREE!!!
