feel sorry for you!
i fond that sumtime if a couple wont getting well during breeding, the male will turn to be 'sad' or 'dissapointed', and will lose color and ly on the bottom, seem like lose mojo or someting, so i think if they do not get well during breeding we should separate them immidiately. also, in Tailand, people keep them in seper jars, and use barrier to make sure males do not see each others often(maybe twice a day), and as long as they see each other, they are excited, and will starting showing off! they call it 'trainning fighers'. good luck with the babies!! all the best!
