purple tang

[naesco]

It is great that you love tangs as I do but you really need to carefully consider providing them with the optimum conditions. You do don't you?
So plan to move up a couple of feet to a 6 footer and add tangs to your hearts content.

IME it would be poor judgement to add a purple tang which is known to be aggressive to a small tank that already has two tangs in it as has already been posted.
