It’s good that you will concentrate on breeding. Then you should follow the hints that Martin Hallmann and I give in our Paro-book (P. Finke/M. Hallmann: Prachtguramis. Aqualog 2013; available for example by Amazon).
This means: nearly no substrate (a layer of one cm only or nothing, you should use no plants growing in the ground; they always influence the environment (some floating Ceratopteris or Javamoss are good), ten or fifteen dried leaves of beech or oaks instead on the ground, a cave, wood possible freshly taken from a peat swamp (old dry wood may change the water parameters to large an extent), a leaf of Terminalia catappa on the back glass, some alder cones, that’s the essentials. When you are more experienced, you can make exeriments with mor plants, but you should omit the Crytps. In most Paro-biotopes are no submerged plants; they don’t need them. Try to forget the traditional way of aquarium set ups; it’s blackwater aquaristics which you are going to be acquainted with.
