Ok great thanks, will do that. Somehow, the skinny one with the ulcer on her eye is still alive! She still hasn't eaten anything. I notice that she has a yellow area in the area where her thigh meets her body, and also where her arm meets her body. It looks like a yellow powder, like pollen, and doesn't come off in the baths. Another frog now has it in the area between his thighs and body. Any ideas what it might be? One of them had a poo with mucus in too, if that is a sign of anything....?
