Thanks James.
I went to a vet today with 2 Snakes that are not eating and 3 deceased ones. Had to drive 60miles because they are the nearest.
Anyway the verdict is an internal virus, they opened up a Floridor Blue and found it's liver was infected and they are sending it for a virus Autopsy which i should have a final answer next friday though i have just had a phone call to say there is only one place that can now do it and it will cost for a full Autopsy and not just the viral which is all we need is £250.00 but if it can define the dease and keep the others alive it will be worth it.
They think it begins with An or am but that is why they were sending it off to confirm.
