Made some fruit fly cultures and it actually worked!! I used the frog forum media (John Clare recipe)----Thanks John ---- posted on this site, but used 1/2 vinegar and 1/2 water instead of the methyl paraben (tegosept). I'm trying to keep it as natural as possible, and I'm pretty sure they don't eat tegosept in the wild. I just wonder what the long term affects are, if any, would be. This is my first attempt at culturing fruit flies. When I opened the jar it smelled VERY strong. Should I use less vinegar? I just wonder if the frogs can actually taste the vinegar. Has anyone used a recipe like this for any amount of time and had any ill affects? What about not using any vinegar, has anyone had any success that way? If your reading this post, just jot something down...any info helps....even if you don't think it's important.....I notice a lot of people read posts but don't ever say anything....So, come on, help me out...I promise I will pass the info on to the next newbie who needs this advice!!! You guys are awesome...Thank you
