I have both in separate tanks right now but i was wondering if i could mix them later on when they are about the same size. Right now the atf is about 4 inches and the AP is about 6 inches. I was thinking of putting them together later on when they are like 8 inches. What do u guys think. I think they would look awsome together but i dont want one or the other to get killed. Let me get your guys' opinions.
