Peter54,
I am truly sorry to hear of your devastating loss. You are such a meticulous and devoted breeder, and to have such an unforeseen thing happen is just the pits.
I have avoided getting agalma myself having heard of this odd disease, which seems to be some sort of virus. Is there anything you can do in the way of supportive measures in the hope that some of them can overcome this? It reminds me of feline leukemia, a disease I am unfortunately familiar with.
