Exactly :) Which is why, even though some people feel they should be culled I say hold onto them and give them the time they need to be pretty! Because for instance... In a spawn where most of the fry end up dark blue, you might just get the runt who turns into the dark blue with metallics, or something. Or might have the best finnage. You never know - which is why research is where it's at :) asking questions on here too!
Breed for the breed, not for the money; the words any REAL breeder would understand.
You must know nothing in order to know all, for all is nothing and nothing is for all.
