Can someone help with what to do with treating an American bullfrog (not positive it is this species) that I suspect has Chytrid fungus. I have a couple of frogs in a small backyard pond that seems to be affected. One frog has a greenish color around the neck and on the head. He is having a problem sitting upright and staying/swimming in the water. I'm looking to find out if there is a way to treat the pond and/or the frog if indeed it is fungus problem. Any ideas or suggestions as to what the problem maybe or the treatment is greatly appreciated.
