I know this is an unpleasant topic, but I'm curious about other people's culling practices. Personally, this is my first spawn, so I'm still figuring all this out. I'm still in the process of culling the weak, tiny, and deformed babies from my orange x cello HM spawn. I'm doing stage 2 of my culling process tomorrow, at 10 weeks. Stage 1 consisted of rounding up as many tiny/deformed fry as I could catch, and taking them down to my LFS to feed to the oscars at 6 weeks. Since then, I've had a few that needed to be culled for humane reasons: these have been fed to, get this, my hamster. I've heard of folks using frogs to cull fry, but mine seems totally uninterested. So, I figured I'de give the hammy a try, he eats anything. This is so much easier than driving down to the LFS, and its very quick.
How about y'all? How do you cull? And when? What do you consider the most humane way of culling deformed or weak fry?
