Pieces are lacking swim bladder, which prevents them swim. To solve it give lateral jumps and fastened to the mouth to the substrate, to avoid being dragged by the current of the rivers they inhabit. The fins have spines reinforcement, Similar (although not as strong) those of the Hypostomus plecostomus, with which it shares is cleaner fish nickname or Limpiacristales. It does not have thorns on the adipose fin and caudal fin. As for the differences between male and female (sexual dimorphism), They are almost negligible. Maybe, the female is more round and larger, while the male is more stylized and somewhat smaller.

The group must consist of more females than males, the chase until they are accepted. Got a time, females lay their eggs (between 20 Y 40 per copy) on the walls of the aquarium or on the leaves of plants. The sunsets are not very abundant, and parents abandon their eggs, we can pick up and move to a breeding tank. Hatching occurs at 2 O 3 days.
