I plan on introducing them into the tank after lights out on Saturday.
It's. 125 gallon tank. It's 72 inches long.
60 inches is about 5’, to me that fish will be a pain in that size tank, however in a 6-7’ tank these fish aren’t aggressive or as aggressive.

I would leave it, also how is it a 125g but 6’ long? Is it just a very shallow tank? Depth and width would also be useful - Again, what is this third tang you talk about? I have never heard of the name you have been mentioning. Now I know it’s 72” long it’s doable but I still think it’s small for these fish but that’s me being picky by 12-24” of room. I find the PBT will become an absolute mennace in any tank less than 6’, one of my old LFS’s had a 4-5” PBT in a standard 6’x2’x2’ tank, there was only about 4 fish in total in that tank and when they tried to reintroduce a Chelmon marginalis the PBT went mental. I wouldn’t want to know how a 8-9” PBT would act in that size tank, this aggression was worse than the juvenile sohals you see for sale.
I kept trying to look it up but it came up with the Blue hippo and a Yellow tang, I don’t think 3 tangs would even try to get along in that size. If it is a sailfin then I can assure that the PBT will be highly unhappy. I mean koles get 4”, PBTs get 8-9”, Both sailfins get 14-16”… I don’t see how a 14” fish would thrive in a 6’x18”x22”. To me that’s just looking for ich, maybe it would thrive if there was only 4 fish in the tank and only 1 or 2 of those was a Tang but I don’t see 2 fish that reach close to a foot and bigger as thriving in a 6’ tank. Add to the fact body shapes in sailfin tangs and PBTs are very similar, that’s asking for aggression unless it’s Atleast 8’ tank (Minimum IMHO).
The right 3 could work. I agree powder blue and sailfin aren't good long term choices. Ich, you just have to QT.
I agree on how the right 3 could work but trying to find the right 3 would be hard, I think maybe a convict tang, the smaller bristletooth tangs and maybe a Caribbean blue or Goldrim at a push but I would be cautious of the two Acanthurus tangs. I think the Goldrim because they aren’t as active as the other four in the Powder tang complex.
I got told a bristletooth and Goldrim would go badly too (This was in theory I got a 5-6’ tank and then went the Goldrim route). I find that the Goldrim body shape and bristletooth body shape is different so I don’t think it would always go wrong, but it could go wrong. I don’t know about aggression in goldrims because they get overshadowed by the tangs that are brighter colours so collectors don’t tend to get them since they don’t make as much money as PBTs and Achilles. I often sit in my LFS and watch the fish for Atleast 30 minutes to see how they behave every week and it has always been the “true” Powder tangs that have been swimming nonstop but the Goldrims and Mimics seem to be less pacing/stressed and more chilled out. I also find that the 3-4” sized tangs tend to be calmer because they aren’t established to the wild enough to have the strict herbivorous diet but aren’t too large to be almost impossible to keep.
That was the 1st juvenile gold rim I've ever seen. It was a dull gray with the gold outline on the fins. I know they are not very common. I think mimics are very underrated. They have a very unique look overall with the flowing wide fins. When they flare out they look really impressive. All of mine are the same shape and I was surprised they didn't have any issues when added. I'm happy because they graze my rock work and frags non stop eating algae.
I had a Gold Rim tang and a Tomini tang in a 120 gal 4ft tank. I had no issues between the 2.
