hey, umm just to let you no if you are breeding gourami's for the first time buy a complete new tank! set water at 26 degress have light and reids! black pebbles and a small piece of drift wood. have one male and a very attractive female and in a couple of days you should see bubbles appearing around your tank! they will form togeather into a nest that is when you no for certain that they will breed! i brought 2 gourami's on sunday and put them in tank monday night bubble nest appeared!
hop this helped
