I just discovered that one of my Kings and one of my Corns are showing signs of scale rot. The last time this happened a few years back, I remember treating w/ Betadine diluted in water, but I can't remember the dilution ratio. If someone could refresh my memory, it would be greatly appreciated. Thanks!
The odd thing about this scale rot is that it's starting on the tops of their heads, rather than their bellies. Has anybody else seen this?
