yellow eye/ bristle tooth tang

[JReefaddict]

so i have a 6 foot 180 gallon reef, the tank currently has a yellow tang, blue tang, and powder brown tang and i want to add a yellow eye tang but im not sure how much of risk there will be of fights, any input?

How big are each of the fish? How long have they been in the tank? How much rock do you have? Is there any aggression currently? You say blue tang, I assume you mean a Atlantic blue or PBT and not a hippo?

It's a blue hippo. That one is the biggest of the 3, About the size of my hand, 4" give or take? The yellow tang is a tad smaller and about the same size as the powder brown. The yellow tang and blue hippo were put in together about 6 or so months ago and the powder brown was put in I'd say 6 weeks ago, there doesn't seem to be any aggression, they all keep to themselves and the powder brown likes to hang out with my 4 chromis. Don't know the weight of how much rock I have, but it stretches the length of the tank and goes about halfway up. Still adding rock here and there whenever I find a piece I like

I've got a yellow tang in my 120 that is the size of my palm, then a couple months later I added a kole tang that is 1/2 the size. The kole tang spent a day in an acclimation box, then I released it and turned off the lights for 24 hours. No aggression from the Yellow tang.
