adding Purple tang with yellow tang

[Mengchhorn Chhun]

Hi, currently i have a 120g DT with around 3inch yellow tang already in it and last time i do add the small purple tang to it and it been harass by the yellow one all the time till i have to get it to other tank. If i add another big one around 5inch purple tang to the DT will that yellow tang still harass him?

Following. I have a 4’ 120 and would like to try to add a small yellow and small purple at the same time.

as i know it gonna ok to add purple tang before yellow tang, my LFS said yellow would be the last to add since it so aggressive with other tang.

I run a 220 with 3 3” yellow, a 3” purple, a small kole eye, 2 browns, and until last week a 5-6” orange shoulder and 6” inch sail fin. When I added the three yellows, only two were aggressive, and that was towards each other. The purple never paid any attention to the yellows. I run a lot of live rock in the tank and in the 200 gal sump. The live rock and extensive aqua scape provide plenty of diversion and hiding places. The reason I moved the big guys out was that it is an SPS dominant tank, and I am still learning how to grow the buggers. The two large fish kept knocking over the corals, complicating the already challenging process. The point is: just like raising kids, keep them occupied and interested with new tank mates and scapes, add the new guys at night, (well, making new ones is fun any time of the day or night), and be ready to adjust when relationships change. Like anything else, if you have time and observe, you can adjust almost anything.

It’s hard to predict how resident tangs will react to a newcomer. Generally, purple tangs are more aggressive than yellows, but there are individual exceptions. I’d also suggest that the plop-and-hope approach is poor practice. Use an acclimation box to gauge potential aggression and tape a mirror to one side as distraction. Even with all that, the resident aggressor may need to be sumped for a while. 120 is tight for more than one zebrasoma, and lack of space exacerbates aggression.

Just an update, my purple tang arrived yesterday and after i put him to the DT, he seem really fine swim around and doesn’t bother any other fish also the yellow tang wouldn’t really care much to him either, so what i though is that because of the size of the purple tang that why no one bully him.
