Gray Tree Frog with Cuban Tree Frog?

[spawn]

I don't even know why you would try mixing them. Cubans are wiping out native frogs in the southern states of the US, including cinerea and versicolor. While a full grown female Grey would probably be too much to handle for a Cuban, Cubans of ALL tree frogs I've kept, are the most voraciou feeders. Much more voracious than Whites. If I missed a feeding for a day or two, they would LUNGE at each other. Not only that, but Cubans have very toxic [relatively] skin secretions.

Cubans are the hardiest frog ever to be kept in captivity. They can be kept in the worst conditions and will do fine. Greys are rather fragile in comparison. Mixing greens with greys would be one thing. Just do a little research on the Cuban tree frog in Florida.
