Well this group is behaving in a similar way to the original frog. Almost never moving, not eating that I'm aware of. There is the odd poop appearing now and then though, and they do go to the water bowl to hydrate. The sores are clearing up nicely and don't appear infected any more. All movements are very lethargic even when picked up and this morning this guy was sitting on the floor with his mouth wide open and a very dark colour. I moved him to edge of the water bowl but he doesn't look in good shape to me:



For comparison to the 'normal' colour:



On the other hand, I managed to pick up a further 4 yesterday which had come from the same Hamm show and were in a shop on the south coast about a 4 hour drive away:









This group is like chalk and cheese compared to the others, they were very active and climbing and leaping to get out of the travelling box both when we put them in and on arrival back home. Two were even in amplexus at the shop (where they were in a relatively small vivarium with moss, branches and plants and being kept moister than mine).
Much more what I would consider normal behaviour compared with mine which sit there and remain asleep even when picked up. More fuel for the mystery !

I'm still awaiting results of chytrid and ranavirus tests...
