great discussion everyone! it would be so great if anyone can do an actual scientific work on a subject.

explanation of more resistance of a frogs from a pet shops is because for them it is survival of the fittest, can you imagine what a hell road they need to go before then end up with someone caring, so many frogs will die, only survivors that are more resistant to everything will be sold. A frogs from a breeder are more lucky and these who would have dead going through pet stores, will be perfectly happy and healthy here. These frogs can be objectively be taken into consideration when comparing, as one group is already more resistant to begin with and will respond better to any changes in environment.
