Ya inbreeding is not good. I love my fancy guppies and goldfish. But i know how weak they are compared to wild fish of the same species in the same environment. And it is the going trend in the guppy community of which i am a big part of that breeding traps do not work. But if you guys wanna give out bad advice and turn off newcomers to the hobby just like poorly knowlaged pet store people do , go right ahead i cant stop you. I have 50 newborn amnd 35 1 month old guppy fry from 4 hb females and they were all simply removef from my planted colony tank and put into ten gallon grow outs.
