I discovered this breeding a large form of macmasteri. The female would preferentially oviposit in the smallest of possible niches (e.g. crevices in bogwood). The male positions his vent over the opening and hovers (and presumably releases milt). After, he will vigorously tail slap the area, getting a current going through the egg containing hole.
