Vinegar eels-$5/concentrated Tbsp
These are starter culture. Extremely easy to culture
All you need is oatmeal or bread and a sprinkle of yeast. Expect some worms to crawl on the sides of the wall at 1week. I feed them maximum 3 days after free swim.
50% Apple Cidar Vinegar
slice of apple
play the waiting game expect an established culture in 3-4 weeks =]! replace apple every 3 months at most.
I use them when i encounter swim bladder disease they are great because they swim around and smaller than microworms.!
