Incorrect. Male and female bettas can not be housed together. The aggressive male will chase and eventually kill the female betta. They should only be kept together for temporary spawning purposes.
YOu may also not get the luck. Females and males will not always take to each other from what I have read and it can be pot luck sometimes, may take more conditioning though and work with a chimney (and patience). Both can be so tempramental, be careful with them with each other and with those other fish..
