Great post Craig...lots of great info here.
I know it probably varies greatly on conditions & species, but how long does it take for Tangs to grow to maturity...
In my case, I have both a ellow Hawaiian Tang - Zebrasoma flavenscens & a Pacific Blue Tang - Paracanthurus hepatus, both juveniles that are doing well in my 55 gal. (48"

tank. --
How long would you expect I can enjoy them before they start to get too big for tank? ???
Once again, we "beginners" have much to learn.
