Grey Tree Frog Compatibility ???????

Personally, I wouldn't mix any species together.

Frank Indiviglio discusses keeping Grey Tree Frogs with other frogs and toads in one of his blog entries at That Reptile Blog if you are really keen on mixing animals.

He says he has kept a Gray with a Barking. I tried that... No more Grays.

What about canyon treefrogs?

I am correct in assuming that it didn't work out?

I've only mixed when I've had large tanks and personally raised the amphibians myself (from tads). I've kept wood frogs with toads and spring peepers with toads. I currently keep a toad with my grays but the tank is so large and the tree frogs stay high up. They're all local animals and I'm confident in my abilities and in the set up but this is a far as I'd ever go with mixing. So far so good.

I don't think I've ever mixed anything that I caught in the wild as an adult. Do Barking and Gray Tree Frog distributions overlap?

I have a barking tree frog with some green tree frogs and a couple squirrel tree frogs, none have been eaten so far and they have been together for about 6 months.

My barker youngsters ate my gray youngsters after 3 months together. If they can eat gray tree frogs then they could eat squirrel tree frogs.

Its not a good idea to house multiple species together. See my response to your other post in New Vivarium

Similar size and habit to Grays. So possible food for others.

Wait can they be kept with grays?

Hmm, probably from a size and habit point of view, but they do not overlap in natural range. Canyon Tree Frogs are protected over most of their range I believe.
