I am greatly confused! For the second time, I have had a frog supplier tell me not to put the blue color White's in with the green. I have 5 baby green colored and want to get one or two Australian blues. I know they originate from different areas so does this mean they shouldn't be in the same habitat? Some people tell me its okay and I have seen pics of this on this Forum, yet some say its not a good idea. Opinions?
