Hi to everyone Just found two female nijsseni yesterday, after searching for a few months. All ready have two males (full grown) in a 50 gallon community tank. Should I put the two females (a little over one inch long) in the 50 gallon with the two males and let them pair off. Or put one or two pairs in a 15 gallon tank? Or put one male and two females in the 15 gallon tank? Thank You George
