Greetings from PA. I have had two American green tree frogs for about a year and a half. Just got a whites and I currently have the three of them in a 20 gal exoterra terrarium. I'd like to think that I did a lot of homework before I bought my original 5 frogs from naturecoastexotics.com (two red eyed tree, one Vietnamese blue tree, and two american green tree). I was told by whomever answers the customer emails that all 5 could be housed together in a 30 gal terrarium with no problem. This proved not to be the case as the both red eyed tree frogs and the Vietnamese blue tree frog died about 6 months after I had received them. I made sure the cage was warm and humid, lighting was correct, and the frogs were fed every other day. Now I've only had the whites for two days and I plan on moving him to his own terrarium (after what I have read about keeping different species in the same cage), but I am looking for some insight. Is it necessary to move the whites tree frog? and if so whats the best way to go for a home him/her. Thanks!!
