Microworms are the perfect first food for fry, and they can easily complement brine shrimp in a baby fry’s diet. They are easily cultured and can be available on a continuous basis to feed even the largest batches of fry.
Microworms are not worms at all but actually small colorless nematodes, approximately 1 millimeter long. They can be cultured easily by the home aquarist. Microworms are not sensitive to their environment and will thrive at most room temperatures. They are easy to feed to your fry and because they wriggle around so muchwhen they are in the water the baby fry, which are attracted to movement, will take them readily. They are only for babies however, as they are way too small to be fed to larger fish.
As soon as your microworm culture has started, the only attention it requires is periodic sub-culturing. This is done to avoid any offensive odors caused by the culture medium going sour. It also prevents the culture from drying out. I will provide you with instructions on how to create a sub-culture upon purchase. A single culture can be sub-cultured into as many cultures as you may need to meet present and future feeding requirements.
