I Have a pair of blue Gouramis (3 1/2 inches) in 20 gal tanks with 4 4" oscars about 2 months ago. Starting last week, the male Gourami has started to blow bubble nest. I want to get them to breed, so I need some help from some gurus who's bred gouramis before. Such as what tank size?, filter yes/no?, substrate?, food?, water temp? light? and the process to get them to breed. Thanks very much, I would be happy to give some fry away too. (if I successfully breed them
). TIA
