Live Vinegar Eels in Vinegar

Turbatrix aceti. Vinegar eels are one of the most stable live cultures you can keep to feed fish fry, even when they are still too small to eat baby brine shrimp. They are also difficult to over-feed, as they will remain alive in the aquarium indefinitely until eaten. The culture can be neglected for weeks or even months at a time and still be viable.

Culture comes in a bag or 8-ounce bottle with a 50/50 mix of apple cider vinegar and water.
