I have kept a Purple Tang and Blue hippo Tang together. They would occasionally spar but for the most part they left each other alone. I now have a Purple Tang about 6-7" and a Powder Blue together in my 120g and they get along just fine now although the P.Tang gets a little aggressive during feeding. The P.Tang however, does like to harass my larger Moorish Idol for some reason.
The bottom line is that you never know whats going to happen till you put them together for several days. _________ 75g reef with Nova Extreme 8 bulb HO T-5 lighting, refuge, Remora skimmer, DSB, Seio powerheads, Acro's, LPS corals, assorted zoo's & mushrooms, Yellow Tang, Maroon Clown, Blue Cleaner Goby , Cleaner, Fire and Sexy Shrimp, Coco Worm, T.Crocea Clam, Derasa Clam
