Enchytraeus buchholzi Vejdovský, 1879  [1]

Enchytraeus buchholzi, Grindal worms, (described by František Vejdovsky in 1879) are enchytraeid oligochaete worms.^[2] They are found in temperate meadows and disturbed roadside verges. The scientific name probably covers a group of morphologically indistinguishable species, which would complicate their use as test species in substitution for E. albidus, a species commonly cultivated in the laboratory for toxicity tests, according to OECD.^[3]

For aquarists "Grindal worms" are treated as smaller relatives of whiteworms, but usually only grow to about 10 mm and thus are an ideal size for most small freshwater fish, both adults and larger fry. Mrs. Morten Grindal, of Sweden, who was prominent in the development of culturing techniques for whiteworms, was apparently the first aquarist to isolate this smaller species. Grindal worms can be cultured exactly as whiteworms but are a much more adaptable species and have a greater tolerance for warmer temperatures. Maturity has been reported to occur around 16 days at 20 °C, the clitellum forming when the worms are about 3~4 mm. The generation period (cocoon to cocoon) is about a month at 20 °C.
