Dmac,
There is a little problem with keeping red eyes and tigers together.
Firstly, and most importantly, they have different climatic needs. That means your red eyes are forest/jungle frogs who enjoy humidity and the high cover of moist, tropical plants.
Your phyllomedusa, or monkey frogs, are actually frogs who live in a more arid, dry condition. They cannot tolerate the humidty that the red eys must have!
So mixing the two species and trying to have them both live and thrive is not possible.
You really shouldn't mix species, even if they come from the same climate, because even though the tosins in their skin reduce upon entering into
our vivariums (they aren''t eating the same insects that made their poison glands as toxic) they still are toxic enough to frogs of other species to cause them harm.
And lastly, frogs are territorial in nature and don't like sharing space with other frogs or toads, or really any animal that eats the same things that it does. (bugs)
Your vivarium will look great with a couple of happy, healthy red eyes in it, trust me on this! And they need a tank that is about 20 gallons, taller than wider. This site has plenty of great vivariums to help you in finding one right for you.
Good luck with your frogs buddy!
