adding tangs in 90gal mixed reef

[Madreefer]

They're same body shapes so I can see some fighting to possible death. Plus all 3 might be a little tight for space in a 90G.

Yes, I am expecting 3 tangs are tight in my tank. I just can't make up my mind which one. I never thought about purple tang before but they are a half price at our LFS.

Two tangs max. I would say in your size tank (hope you plan an upgrade).

The box I would build would be at least 1' x 1' x 2' in order to fit into your 90g. A bit bigger would be better.

Go with Purple. Powder anything tangs are terrible ick-magnets. The stress will likely cause a big outbreak that will kill at least the Powder Brown.

Same shape yes, but the isolation chamber worked for me to get a school of 6 YTs in my old tank years ago, one at a time.

All I can say is that I had a yellow tang and a powder brown tang in one of my nineties for two years, only to come home one eavening from work to find the brown dead on the bottom, and the yellow died a few days later.
They tore each other up quite badly.
I'd never seen the aggression in that two years, and after it happened, I had plenty of "I told you so"s from other hobbyists.

OK, thanks for your info. I will go for purple tang. However, I'm thinking to do a little bit rock work change before Xmas. Do you think I can keep a baby purple tang in temporally 20gal SPS tank for few weeks? I only have a 3inch lawnmower blenny in that tank.

If there is much of a size difference, especially with the new tang being much smaller than the old one, that can be a recipe for disaster. Much safer IME if the new tang is bigger (i.e. tougher) since the old tang will have home tank advantage, so to speak.

Well, purple tang I see at LFS are about 2.5 inch and my yellow tang is little bit bigger than 3 inch. That why I am thinking to put Purple Tang in 20 gal for few week and change rock work in my 90.
