I've bred before, but never bettas. I worked with easy breeders such as danios, platys, and guppies. I'm now ready for more of a challenge! Plus it's a much more rewarding fish to breed; with so many identifiable traits :)
I know breeding pet store bettas is frowned upon (mostly veiltails), but what about a DT from a pet store? Will it still be a "mutt" of bad genes? I can definitely buy a breeder male from AB, but I think Harlequin is a fairly well balanced DT (from what I can see), and he's eager to breed. I know he'll be carrying genes I have no idea about... is it ok to do one spawn and cull off a lot of fry to see how they're turning out?
There's obviously a lot more to think about when breeding bettas, especially since I want DT and marble. Advice please! :)
