What can I get to go with a bully bristletooth Tang

I would consider putting a background (black contact paper) on the back, and moving the rockwork against the back wall. Building up the hardscape around the overflow works really well, as there are the dark corners where the overflow meets the back wall at a right angle that make a good start on a great little hideaway (and are a two-points-of-contact spot to help stabilize the rocks). There's really not that much for good hiding spots in there, judging from the photo -- it is all round rocks, with little in the way of dark crevices.

Just my opinion on fighting with trying to keep a couple tangs in a 90 for quite some time (my 15 year old yellow died within the last year, and my same-age scopas is still with me). If it helps you, great; if not, maybe it will another reader. Seems to be an extraordinary many tang issues reported here, so I think all possible improvements are worth considering.

I appreciate your feedback! Sorry to hear about your yellow, I didn't have my older fish for very long, but I was extremely attached to my bird wrasse and heni when they passed (estimated age was over 12) that's great though that they lived to their full lifespan.

The back of the tank actually has black contact film already and that wasn't working so that's why I did the white paper (which helps a lot)
And the rockwork may look like it doesn't have a lot of hiding spots but it definitely does, I purposely built the rockwork around the back mostly and around the overflow to include many caves and good hiding spots because I knew i needed more spots than it was previously set up as. I'll see if I can get some good pictures

I no longer keep tangs (except a lone flame tomini), but over the years I’ve kept many, from smaller peaceful guys to Gigachad “kill others on sight” purples and scopas, etc.

The only things I’ve found that help alleviate angry behavior are (a lot of) horizontal swimming space, plenty of places to sleep, feeding heavily (no one resource hoarding), and making (carefully chosen) additions at the same time if at all possible.

And sometimes nothing helps, and you just happened to get an individual that is a full time warlord.

I hope I don't have a full time warlord hahaha
I have taken the previous advice over the years of keeping them well fed with lots of hiding spots (my new rock work I made sure there was lots of caves) and also horizontal swimming space. The only thing I think I can really work on is the carefully chosen additions

Just for everyone curious/for reference, it is really hard to get all the hidey spots because a lot are hard to see unless you're in front of the tank, there are spots against the glass that cannot be seen well. But I do have more rock I can always put on the backside but I like to keep the front clear for swimming. In total there are probably about 6 caves that have a sandbed

Most of the caves are on this side, the tang has his bed here in one of them

This is his sleeping spot

Other side of the overflow are which you cannot see the caves

Yeah, thanks. Having kept them alive for a lot of years, but not doing so very well (had some HLLE, and just not enough room to live well, IMO) helped me to rethink how I want to approach fish care going forward -- mostly, trying to provide a little more than just years in a tank.

Thanks for the additional pics. I misunderstood a little, before.
