D. Hydei Carotenoids?

[Jesse]

I recently purchased a vial of D. Hydei fruit flies from my local family owned exotic pet store. Since then, my notophthalmus viridescens viridescens morphs seem to have gotten more orange spots. Do D. Hydei contain carotenoids? Is it in the eyes maybe?

Unless you are feeding the flies a carotene rich diet, they should only contain minimal amounts and not necessarily of the right kinds of molecules. Has there been any other change in their diet?

[Jesse]

Nope. All I've been able to get the morphs to eat are fruit flies. Maybe there are carotenoids in the medium try are housed on? It's some blue goo stuff. I don't know what it is. They had eaten lots of Daphnis as larvae but that wouldn't suddenly change the color woul it? That would have happened right when they morphed right?
