In a word, no. You should never mix amphibian species. To do so is to risk cross-contamination and infection. Also Agalychnis callidryas (red-eyes) get big enough to eat the much smaller Dendropsophus leucophyllatus (clown treefrog)
Also could you please post your location and country in your profile? It makes it much more easier to help you.
With that being said, welcome aboard.
