Hi I have had my American Green Tree frogs since last Christmas, all was going very well until last Friday when I noticed that one of them was staying in the same place for long periods of time and not hiding away in the way when he normally does. Over the next couple of days I kept an eye on him and everytime I open the tank he would just sit there not moving. It was now been nearly a week, he is not feeding, has got very weak and very thin, also has gone a very strange colour, barely green at all. Hve tried feeding by hand but no interest at all. Opinions would be very gratefully received as im now extremely concerned. Thanks Nikki
