If you have a pair, best thing is feed well with blood worm, prawns etc, drop the level of the water,leaving for about a month, no waterchanges, then, preform a large waterchange,around 50%...see what happens, make sure you have it well planted and no other tank mates...
Do they flirt alot and show of there fins? may even as my channa did preform ball drops,where they wrap as a ball at top and drop all way to bottom, if they are doing this you could well be in there.
