How Poison Dart Frogs Adapt

I think Poison Dart frogs will adapt by losing coating or something that keeps them warm, because of global warming. I also think that they will adapt by losing their poison, I think that we will have them in enclosures at some point, where they are protected. The last way that they will adapt is; they will get bigger because of the crazy amount of bugs and crickets that will be enlarged by the moisture.
