My clarkii clowns easily have grown faster than my tangs, , my female is the size of my hippo, bigger than my yellow. My hippo has grown a bit since adding, not much though. Yellow and sailfin have stayed the same, as has my blue throat trigger, all are just fatter.
I noticed the female clarkii's growth started right after moving her from the 55 gl to the 180. Maybe size does matter (tank).
