What order to add these Tangs in?

[89Sem]

Right now I have a 125 4x2x2 I have plans of adding an additional 6’ later on down the road.
Love the look of tangs I’ve been reading up and it often says to add them all at once. But my understanding is that some are less aggressive than others. I want to add a Hippo, Purple, and either most likely a Powder brown, or White tail Bristletooth ( instead of the brown )
What are your thoughts on this?

All at once is best. Get them small 2.5 inches or so. If adding one at a time, Whitetail, hippo, purple.

Hippo, then Bristletooth, then purple.

I have over 10 tangs in a 210 gallon tank. All at once. If you have more than one of the same example yellow tangs use 3

Firstly I’d definitely do the white tail over the powder brown lol but that’s just personal preference. And if you can I’d add all at once.
