Strawberry Poison Dart Frog

My animal is the Strawberry Poison Dart Frog. Currently the population isn't highly endangered, but the species are dwindling. A fungus/ disease called Chytrid has been wiping out this animal. This disease is transmitted through a frog's skin. The frog breathes through its skin and when the breathing mechanism is compromised, it's hard for a wild animal to survive. Chytrid is also very heat sensitive. Anything over 37 degrees celsius will slowly kill the fungus. I believe this animal can survive through homeostasis. When the frog gets infected, it could learn how to temporarily regulate its body temperature roughly 3-5 degrees higher which would kill the fungi. This is a major adaptation, so I believe it would take roughly 300-500 years to start seeing changes. The animal would also have to get used to temporarily high temperatures.
