due to the ascorbic acid content you shouldn't give the green stuff to simpler. their systems can't handle citrus fruits because of the high level of ascorbic/citric acid. not only has it been added to the drink but it also contains pineapple and lime juice. anything citric you want to avoid.

now for a treat he will really love and that is also good for him, try sarah milroy's "super mixture."

1 jar chicken baby food

Blend everything together and...voila! Super Mixture is born. This recipe was given to me by a friend, and I have to say that it's worked out great. I changed it a little (I cut off the strawberry seeds because I've heard some weird things and they don't like to eat them anyway), but the cresteds love it! Every one of my geckos lick their dish clean when they get this stuff. Keep in mind that the recipe can be reduced and it's not set in stone, you can add another peach, take away a banana, etc. Prepared like this, it lasts me a while, and I have a lot of geckos. Sometimes I'll also add a little Herptivite or Rep-Cal.
