Hi, new member here. I am having trouble with mating tiger barbs. I have six on them in my tank, and they are now fully mature. I notice the difference between male and femail (red nose, mouth and fins) and have taken one male and one female out and moved them to a set up breeding tank. They have been chasing each other for days...but nothing more. They are also not eating. I'm getting worried. Should I put them back in big tank? Maybe they don't find each other attractive

Anyone have information for me? thanks, Mary
