Thank you for your advice! The baby whites were not put in with the golden glider and the green tree frog, the vet said it was just one of those things that probably came from the crickets, or their mother although that didnt stop me being paranoid that I did something wrong. I know that its not the best thing to mix the species but the golden and green frog have been together for over 2 years now, they have both been checked and are fine!

I think I will change to eco earth as it seems to be quite commonly used and fairly safe. I am doing their viv up at the moment.
