Hoping to get some expert advice. Made my first culture but 2-3 days later I have some white mold or fungus on the surface of the medium. Flies are still running around. I realized I didn' t mix 50/50 water and vinegar and just used water.

Do i need to throw the batch out?

Can i still feed these to my grey tree froglets? I know I can't use them for future cultures.

Thanks for any advice.
