Niche is completely the wrong definition to look for. Niche determines the ecological postition the species plays within the ecosysten and as anoles and these tree frogs have the same nocturnal waking hours they occur in the same niche.

The small terrarium withing the larger terrarium is less than 1 to 1.5 gallons and would surely be very stressful for your red eyes tree frog, possible resulting in more stressful caused behaviour from your tree frog.


Kisa is 100% right, all species, even species as unthreatening as anoles should be spereated from frogs, as in the wild, frogs natural predators are lizads, Anoles in captivity are harmless to tree frogs, but believe or not, tree frogs don't know this! Even with enough space, these two species do not thrive together - red eyed tree frogs and anoles originally come from different areas so are not used to living together. In the wild, red eyed tree frogs are prone to being eaten by lizards, so are scared of them - ..how long have they been kept together?

Behaviour like position and colour can just be down to mood in frogs, and isn't a reliable source to go on for frog behaviour , so until behaviour gets really strange in frogs, it is nothing to get concerned about. It is anthropomorphic to get concerned over behaviour so until your frog is obcenely different to usual, it is not enough to panic!

hope I can help!
