I had one for 3 years, it came in the tank the latest, in a tank with 3 other tangs, a tomini tang, a hepatus, and a yellow tang... grew and became the boss of the tank. He quarrel every now and then with my flavescens but never cut him.. Since he was so well behaved, i had the "great idea" to add a Xanthurum i had on my frag tank that outgrew that aquarium.. He accepted it well, but my flavescens didn't... He was constantly chasing the xanthurum... after 2 weeks of this, (flavescens after the xanthurum) something snapped on my PBT and started attacking and cutting both of them.. almost killing both... It was my mistake, but he had to go...
it is a beautiful fish, but as stated here before, can be agressive and can kill, so if you go ahead with him, some advice:
1. introduce him the last, or at least at the same time as the lasts fishes you plan to introduce.
2. As stated he has to be smaller than the other tangs.
3. have an overkill UV light with low flow on your return pump to control ICH.. This will save you a ton of money on surgeon fishes.
Good luck!
