Both Whites and Golden tree frogs are found in Indonesia, so they are both found on the same continent and are in the same country. The breeder that I bought all of my frogs from told me that he has housed goldens and dumpys together for years and has never had any problems. I asked him if there would be any trouble with putting them with my dumpy, and he said that if they were the same size, there would be no problem. I feed all of my frogs individually, and all of them are eating, none are lethargic.

I am not trying to be a jerk or anything, but the only people that I have heard say not to house frog species together are the people on the internet. I have two friends that own frogs, and they have two different species mixed also and one has had her frogs for years. I just think it's not a big deal as long as you are smart about doing it :/
