The free-living nematode Panagrellus redivivus (sour paste nematode) is known to many aquarium enthusiasts and fishkeepers as the microworm. It is a tiny roundworm used as the first food for minuscule newly hatched fish, such as the popular pet fish betta. The microworm is widely used in aquaculture as food for a variety of fish and crustacean species.
The microworm is about 50 μm in diameter and just over 1 mm in length, barely visible to the naked eye. It is easily cultured at home on a substrate of flour or porridge.[1]
The microworm has been used in genetic analysis studies, but not nearly as universally as its relative, Caenorhabditis elegans.
