Vinegar Eels
Vinegar eels are tiny free-living nematodes, scientifically known as Turbatrix aceti, that live in unfiltered vinegar and feed on microbial cultures involved in vinegar production.
Vinegar eels are tiny free-living nematodes, scientifically known as Turbatrix aceti, that live in unfiltered vinegar and feed on microbial cultures involved in vinegar production. They are not true eels, are non-parasitic, and are commonly used as live food for aquarium fish fry.
Taxonomy and naming
Vinegar eels are the common name for Turbatrix aceti, a species of nematode. Historical names include Anguillula aceti, and the organisms were first recorded in 1656.
Biology and habitat
These nematodes are free-living and non-parasitic. They thrive in vinegar environments containing microbial cultures and may be found in unfiltered or unpasteurised vinegar.
Life cycle and size
Sources describe vinegar eels as very small, usually around 1–2 mm in length, with a transparent body. Reported life cycles include several developmental stages and an adult lifespan of around 10 months.
Use in aquaculture
Vinegar eels are widely cultured by aquarium keepers as a live food for fish fry because of their small size and ease of culture.
Key facts
- Vinegar eels are not eels but nematodes.
- They are free-living and non-parasitic.
- They can be found in unfiltered vinegar, especially vinegar with active microbial cultures.
- They are commonly cultured as live food for very small aquarium fish fry.
- They are extremely small, usually around 1–2 mm long.
Vinegar eels are mainly relevant to Canadian readers through aquarium keeping and home fish breeding, where they may be cultured as a live food for fry.
