They would be happy together so long as they are close to the same size. You do need a large enclosure for them. If it is 90 inches long that would work great. they need about as much room as american bullfrogs. Be extra careful when handling around other pets. as you may already know cane toads can be very toxic. They do have a large appitite but unlike large bodied frogs species cane toads prefer smaller prey. My cane toads eat more then my pixie frog. but it wouldnt even attempt anything as large as a pixie would. A very diverse diet is important for this Toad.
