（重定向自Vinegar eels）
Turbatrix aceti (Vinegar eels, Vinegar nematode) are free-living nematodes that feed on the microbial culture, called mother of vinegar used to create vinegar, and may be found in unfiltered vinegar. Vinegar eels are often given to fry (baby fish) as a live food, like microworms.
