Cull or not to cull that is the question.

Ok on this batch of angels there starting to look like angels. I do not want to cull to soon since I might get rid of a perfectly good fish. There a month and a half old. Some fish if there grossly deformed I will get rid of. Now the angels are Koi's so I have a large variation in color patterns, When will I know for sure what color they will be? Also on the finer points what should I get rid of?

If you are selectively breeding cull to keep the strongest representations of the traits you are looking for. If not, I would just cull the obvious deformities and sick fish.

Ok i will do that. I only have one trait I would like to develop and that is to get a more of a orange color in the angels since there koi.
