Well I know that title will get some attention

Serious question though...
I have around 8 hybrid, four 1" and about four 3"...all fish that were born last winter/spring'ish and I had no idea they were hybrid at the time but now it's to late to "cull" them. I just hate to kill a fish that is more than a fry, so. I have around 8 of these fish from 1-3". I don't want to sell them and introduce them back into the hobby, yet at the size they are I hate to just kill them for no reason. Yet they are taking up room in my tank. What to do with them??
