Mô tả chu kỳ sống và tập tính ghép đôi Semelparous (Ref. 1998). The female attaches with her oral disc to a rock at the upstream end of the nest. The male attaches to the back of her head using his oral disc and wraps his tail around her trunk region in such a way as to have each others urogenital papilla in close proximity and through muscular contraction of his body assists in the extrusion of the eggs. They vibrate vigorously for a few seconds. This results in the release of their gametes and disturbance of the substrate, which partially buries the fertilized eggs (Ref. 89241).
