A little off topic, 3/4 of my whites tree frogs have nose rub. One has a lot of it on his face and has been there for almost 2 months now, the other two got it 4 days ago. I put betadine on the one with the worst when it happend and it hasn't changed yet, same with the others. It's black lines, or dots not pink like I see in other posts. Does this mean scaring hasn't taken place and I can still setup and hospital tank and apply some silverdine to help prevent scaring and promte healing?
