Red Eyed Tree frog companions???

[killerecho]

The only thing you should keep a red eyed tree frog with is another red eyed tree frog, and even then, only if you have enough room.

I'm sorry to be the one to tell you this, but you'll hear it from others if not me: do not mix species. The risks of stress, aggression, toxins, bacterial contamination, behaviorial conflicts, among other issues (the list goes on and on) that come with mixing are simply too great. I can understand the temptation to do so - I've had to learn the hard way myself - but in the long run, it's better for the animals involved, and isn't that the most important thing?
