I agree with what was said above and that the new frog needs to be a White's. If it were a different species, even if they have the same environmental requirements, frogs all produce a different type of toxin from their skin. The toxins from one frog may bother the other frog and vice versa. Even if the frogs never touch, the toxins would be in the water dish and decorations, etc. Besides, a male and a female pair can be fun to watch. Calling to each other and what not. It may sound crazy, but I believe may pair really do love each other!
