I breed dwarf gouramis.I have floating plants,bare tank bottom.Java moss on bottem.Temp 80,ph 6.8. sponge filter hardly moving surface.Put him in first,for a day,then add her.Do a water change that night.Watch him in case he gets nasty.Its good if you can feed them up on live food before you put them together.I put live food in breeding tank, till i see him building a nest.Get some inforsoria going so its ready when those babies are free swimming.Good luck
