    Hey everyone! I'm new to the dart frog hobby!

    I've been culturing both Hydei and Melanogaster for my Gonatodes (small American day geckos) for almost a year now. Recently I've stared having problems though. The past few cultures have been growing green mold like crazy. I've tried everything that's supposed to prevent it, and nothing works. I've had a tough time trying to find some SuperFly, so I usually just make my own medium. I have played with a few recipes, but generally go with mashed potato based media.

    My last couple cultures of both species have had major die-offs too. The fruit flies will still breed if there is mold, but I'm sure the flies get the mold spores on them when move adults to start a new culture.

    What can I do?

    What recipe are you using?
    What antifungal / mold inhibitor are you using in the recipe?

    Also what media? I noticed a mold problem when I tried out toilet paper roles instead of coffee filters. Now that I have switched back there is no more mold.

    Currently I'm using mashed potatoes, boiled water, powder sugar. For inhibitors I've used both vinegar and yeast. They worked before but the last few cultures the mold grows within the first few days.

    I haven't used anything other than coffee filters personally. Could it just be the flies themselves that are causing this?

    The flies can transfer mold to the new culture. You may want to start with some fresh flies. Understory Enterprises ships SuperFly, and I highly recommend it. Its very easy to make cultures that are problem free.

    When using vinegar are you using it with water at a 1:1 ratio?

    I actually tried cinnamon once, it didn't work for me. But I think it was too late at that point anyway.

    Yeast is not a inhibitor.


    Here are a few easy and cheap to make fruit fly recipes.

    Instant mashed potato: 8 cups
    Sugar( fine sugar you can use any sugar just grind it down until it is a fine sugar) : 1 cup
    Brewers yeast : 1 cup
    antifungal / mold inhibitor 1- 3 teaspoons of methylparaben or Cinnamon or vinegar.
    Then add hot water.


    Another easy recipe is

    Equal amounts of mashed banana and Apple sauce(with sugar)...microwaved until hot.
    Then add enough instant oatmeal to the mixture until it forms a thick but still moist consistency.
    Then add the (antifungal / mold inhibitor) 1- 3 teaspoons of methylparaben or Cinnamon or vinegar.

    Or you can easily just order SuperFly which works great.
