Thanks for asking first! Much better to see a question like that than a thread about a frog injured or sick from being housed with another species
Even if the species aren't aggressive or can't eat other animals, it's never a good idea to house ANY reptiles/amphibians with other species (like anoles and treefrogs). It's almost impossible to set up a terrarium with the best conditions for both species at the same time. Also, even if it isn't toxic to humans, almost all frogs produce toxins on their skin that might harm other small animals, especially if they don't coexist in the wild. Sometimes just the stress of being confined around another species can kill them.
I have a similar conversation a lot when I talk to people about feeding options for frog-eating snakes and lizards. If the amphibian doesn't live in the same range as the snake in the wild, I say don't feed simply because of the toxins they can produce on their skin.
