I have a 6ft guppies only breeding tank. Im doing the standard method: lots of swimming space, lots of surface hiding plants, quality food and no multi tanks or selective pairings. So far so good, seeing lots of frys.
Im corncen, that the community (without selective breeding) will produce duller and duller colours down the generation. Poor genetics. Is this a problem breeders face?
LFS told me this, jut wanting some thoughts
