Herichthys minckleyi protecting their nest in Poza de la Becerra, Cuatro Cienegas valley. The females normally spawn in caves and after a while when the fry gets larger they are expelled from the territories by the male, caring singly for the babies until they are independent. Once the nest is left, caves are cleaned and used by other females. Males are normally black in coloration when breeding or dominant, in the video however the male shows a normal coloration, which indicates it is a large and aggressive male not willing to spend the energy necessary (and risk involved) in showing a full black breeding coloration, size is enough to persuade intruders to get close to the nest.
Herichthys sp. 'white labridens' digging a nest in the calcaeous substrate of Rio Tamasopo, Gallinas river in the Panuco river drainage; San Luis Potosí. Breeding occurs from March to August with a peak in April.
