Am I doing the right thing?

[kougs]

Is it genetics or the larger kids not giving the little guys
a chance? I have 6 smaller Koi roughly 5 to 9 inches and they are approaching 2
years of age. They don’t seem to have grown much since I introduced them into
the pond. When I have feed the kids the little guys make a mad dash to the food
most of the time missing and then immediately head back down to the bottom of
the pond. They don’t stay at the surface and pig out like the larger koi.

I have removed them from the rest of the kids placing them
in a QT with a filter and an air stone and plan to feed them away from the
bigger kids. I'm hoping to give them a fighting chance. Or is it because of
genetics that they are not growing and will stay the size that they currently
are and what I’m doing will not change a thing.

Comments? Advise?

could be they are not getting as much food maybe .

My personal observation would believe me to think it is both... assuming water quality is optimal, the little fish may not be a koi variety that has the genetics for fast growth and it could be they are also not getting enough food.

I don't know... I generally defer to breeders to answer such questions.
