I'll try to offer some advice...
Many people say not to mix any species.. Not to offend anyone here, but many people on these forums are huge reptile lovers and so they will always say not to mix, even though a lot of the times its ok.
But I will tell you NOT to mix anoles with firebellys...firebelly totas leave a toxin in the water and air that will usually kill your other animals (even frogs!). I would suggest putting them with another type of frog.
Pet stores have them with Green Tree frogs, and although pet stores usually aren't very smart, I think this would be ok as long as the cage was high and big enough (75 should do it).
I'm planning to have a few anoles in my 30gal hex with a few red eye tree frogs and a green tree frog. I think it should be fine.
