Are my fishes too fat

My fishes are very healthy, Yellow Tang, Convict Tang, Magnificent Foxface, Square back Anthias, sailfin Blenny are all fat. Very much so that all who come and visit makes the same remark, so i'm wondering if its possible to have fishes that are too fat.



By the way i have no trouble with parameters of any kind and no nitrates or phosphate issues either. I feed twice a day. Multiple sources. Grazer ring, veg clip with different algae , and either Flakes, or Frozen Spirulina mysis . Plus they graze all day on the rocks. I have ahuge clean up crew as well that does a great job no problem there either.



I'm just wondering if i should augment my waterflow for more exercise...
