Thank you so much! It's handy having a Kiwi around who knows what they're doing :P

The way you dust your flies sounds like a much easier way to do it, with the little trapdoor.. I'll give it a go next time I feed and I'll get on to the Vitamin powder sooner rather than later, now that I know where to get it from!

About buying the fruit flies from Animates... we were buying them from Four Seasons Pets, most of the batches died off a day or two after we brought them home, so we don't trust them any more! I'll look into ordering some from Lifestyle Animal & Pet Supplies and maybe start culturing my own.. there's something to be said about the convenience of them not being able to fly haha..

Once again thank you very much
