Purple and yellow tang together

[DKoKoMan]

I may have lucked out but... I have currently living together in my 300g a yellow, purple, powder blue and hippo tang. They all leave each other alone and very rarely show any aggression. I think a big thing is to introduce them together as there is no claimed territory. As long as they have room to establish their own space you should be good to go. Also if they are around the same size that seems to help. By far my worst tang in the bunch is the powder blue. He will chase any newcomer around for a day and then gets bored.
