I would like to breed bettas on the side sometime in the future. It's a prospect that really interests me. So I have some questions based on your experiences:
1) Do you breed for what's in style, or for what you like?
2) On average, about how many fry are hatched and how many die off early after hatching? Assuming no disasters like disease or fungus, or unusual circumstances like monster huge spawns.
3) What do you do with undesirable offspring?
4) How do you cull? Do you euthanize or feed them to another fish?
