You see, I don't think it's the substrate, because it is suitable for amphibians too, and I have used it before, without effects such as these happening... But the specialist over the phone has told me that it does often happen to frogs to react this way when they change tanks... I'll try some of the methods that you've been giving me, I'm meant to phone the vets tomorrow to let them know about the progress anyway, I just got very worried when I saw the frog just sit there with it's mouth open, it made me panic, but it might have just been stress, or the fact that it has never been given any antibiotics before?
I'll keep you informed anyway, thank you so much for all your help folks![]()
