heyyyyyy wazzaaaap froggy fans, im thinking about getting a FBT!

you see, i have an amarican toad, but SHE is rather lonely. i read that AT are very social. so i had the idea of getting a FBT. i wanna get 1 and name him flaming sword. will they be able to live with eachother being two different species? and they wont mate, will they? cause i DONT​ want a thousand tadpoles!!!!!!!
