Rotifers are freshwater and marine microorganisms that we can raise at home and feed to marine fish and other larvaes. Here are videos of how rotifers look and move, and how they are used to feed young fish and shrimps. The second section collects tutorials on how to raise and harvest marine rotifers.
- What are rotifers, what do they look like?
- What are they for? What fish fries will feed on them?
- How do I grow them at home?
- What food do I feed them?
- How do I harvest them?

Rotifers are a group of microscopic animals that live just about anywhere there is fresh water, including lakes, ponds, streams, puddles, ditches, wet shorelines (especially sand), and even on wet mosses. On this page, we will focus on the Collotheca genus of rotifers.
What make us cool:
- Rotifers are the smallest animals ON EARTH: it doesn't get much cooler than that!
- They are multicellular organisms of about 1,000 cells but are only about the size of an amoeba!
- They have complete digestive systems.
- Most rotifers are female.
- Rotifers can reproduce either sexually, asexually, or both!
The rotifers (Rotifera, commonly called wheel animals) make up a phylum of microscopic and near-microscopic pseudocoelomate animals. ... Most rotifers are around 0.1–0.5 mm long (although their size can range from 50 μm to over 2 mm), and are common in freshwater environments throughout the world with a few saltwater species

Rotifers may be free swimming and truly planktonic, others move by inchworming along the substrate whilst some are sessile, living inside tubes or gelatinous holdfasts.
