I'm against selective breeding, but I still keep swordtails and a few others.

IMHO, to selectively breed to get bright dazzling colors, long fins that the fish drags around, and weird growths and stuff like that makes the natural beauty of a wild fish cheap. Also, some of the improvements may not be improvements at all. I noticed that if any wild type looking mollies(large sails, green) find there way into a tank full of white lyretails, they will quickly dissapear as customers by them over the lyretails.
