Yeah I have a purple tang, tomini tang, and a foxface in the 29 but they were all in my tank that was infected with ich. I wouldn't get 2 different fish from the fish store and put them together as one may be sick and the other might not so you would be infecting the other for no reason. I have 2 black ice clowns, 2 cardinals, a blenny, and a fire fish in a 10 but again they were all in the infected ich tank together. The 32 gallon trash can is a good cheap idea for more volume. They are $10 at Homedepot. Or you can hit petco and just get a 55 for $55 if you want to extend your water change times and give the tang more room.
