Size is mostly determined by genetics so large parents produce large offspring . As to body shape a mud pond helps greatly but a major factor are seasons . I think that control of feeding is more difficult if you do not have seasons . You really need to have seperate ponds for young fish growing and males and females that way you have some control of feeding .

Hi eugene
we do have seasons here in australia but i think too many of us are guilty of over feeding in winter as they seem to be begging for food as you walk up to the pond
at a hobbyist level its quite hard to have three ponds one for growing on, one for males and a larger one for females. Most of the backyard breeders i know tend to have more space for their fry. adult male and female tend to be together, this often results in pack rape and mass spawnings inside the pond several times a year
