Do not forget uneaten worms will die and pollute the aquarium water, particularly in a small aquarium. If left unattended, it can decimate an entire batch of fry in a matter of hours. To prevent this problem, try feeding the fry three or four times per day in small amounts rather than one or two large ones. In all, microworms offer a cheap, simple and nutritious food for feeding a variety of fry. Microworm has as good if not better nutritional profile to that of brine shrimp nauplii; containing 48% protein, 21% lipids, 7% glycogen, 1% organic acids, and 1% nucleic acids. Approximately 70% of the lipids are fatty acids and the remainder is phospholipids.
