Okay, I'm planning my first betta spawn. And I've been doing some research on the dreaded topic of culling. I see a lot of stuff that says culling fry is a MUST if you breed fish or else you won't have space/will propagate undesirable colors/what have you. Now I have no problem will culling and then giving the culls away as pets. In fact my mother works at an elementary school, and I'd be surprised if I failed to find a home there for some culls. But is it really necessary to euthanize culls????
