One of my clients has an 8' 240 (that he stocks himself) with a 14" Unicorn, 12" Mata, 6" Powder Blue, 6" Hippo, 5" Scopas, 4" Yellow, 3.5" Clown, and 3.5" Tomini. They've all been together for 18 months except the PBT and Clown were added about a year ago, and the Scopas was causing grief in another tank and was moved in about 4 months ago. All was peaceful until the Scopas moved in - he picked on the Yellow badly and the PBT, Clown, and a Hawkfish a bit too and had to be removed. His name is Devilfish. The two big ones are buddies and don't bother anyone.

Another has a 6' 230 with a 6" Powder Blue, 5" Sailfin, 3" Purple. The PBT was added last is borderline problematic - he goes after the other two quite a lot. These have been together only a few months and I'm not sure that they will be able to stay together.

I think If you want several tangs you need to carefully pick species that are different from each other and maybe not exactly what you really want, and also different sizes. Plus there are variances in each species and you also have to be willing to remove/trade a problematic one out.

Which species do you have in mind?
