How long does it take for a yellow tang to get a decent size?

Just got a Biota Yellow Tang that’s about 2 inches. Im just curious if anyone knows how long it typically takes for it to grow to a decent size, like 4–6 inches?

It's my understanding that Yellow Tangs grow quickly their first few years. Probably to 4 or 5", then their growth rate slows greatly.

2 years roughly to get 4-5 inches then another 3 to 4 years to reach full mature size I think I read somewhere.
