The yellow should be okay for quite a few years in that tank. Both my scopas and purple Zebrasoma havent grown all that much. The blue will eventually get too big. But small is okay. Ignore the tang police, buy small, most lfs will be happy to either buy cheap or take from you for free anyway.
Not all tangs swim all the time, mine are pretty chill if im being honest, they either swim in a school with my chromis or pick off the rocks.
There will always be some aggression just some species worse then others. You may get unlucky and get a complete jerk!
The other thjng to consider though before getting them, is not all fish are easy to catch haha. My best advise is get a trap!
These 2 should be okay but there maybe some aggression, especially at the start. A little aggression is normal in tangs, its when they deal with too much thats when they stress and die. Try to keep them well fed. I feed nori on a clip as well as frozens and pallets.
If it doesnt work out be ready to catch one before its too late!
Goodluck!
