Have a sailfin tang and a powder blue tang that get along fine just added a hippo tang and the sailfin is chasing him around and the hippo is hiding !!!
Sometimes they do, and sometimes they don't. I think your tank is a bit small for 1 tang, let alone 3. That powder blue is going to end up tormenting the rest of them IME.
I too agree that the tank looks too small for three tangs. Usually in a big tank with different body shapes and different colors you`ll be OK but in small tanks there will just be too much aggression.
