Keep the smaller or bigger yellow tang?

[Aquavaj]

Wish I could keep both but that'll mean 1 less fish from another species that I could keep. Smaller one is about 2.5" and the larger one about 3.5". The larger one will make a better "centerpiece" for the time being but might be an issue if I want to add another tang later on. The smaller one will more likely submit if the new tang or fish is slightly larger.

To be honest, I don't think it will matter in the long run which one you choose.

Tank size, what tangs are involved, swimming room, food, flow, aquascape, etc will determine how it goes.

1 health
2 color (usually associated with health)
3 size smaller is better in my way of thinking.

I’d keep whichever one I had the longest.

If they both get along, I would keep them both. Upgrade the tank later.
