However I find "spazzy" males harder to breed than more mature calm ones
Breeding instincts. The male doesn't have to be vicious .... btw, I differentiate aggressive to vicious. Aggressive will flare immediately but not necessarily attack. Viciousness is trying to kill the other. Some "chicken betta" can be very vicious while some aggressive betta can be very gentle.
IMO, though they are bred to be more docile, breeding instincts will kick in.
Make sure both male and female are in breeding mood before you put them together. If either one isn't, it may lead to disaster.
