Vieja hartwegi (Taylor & Miller, 1980)

Breeding in Santo Domingo River, film autorstwa Juan Miguel Artigas Azas [00:02:34], zrobiono Mezcalapa: Santo Domingo River

Vieja hartwegi breeding in Santo Domingo River, Grijalva drainage [Chiapas]. Pairs keep their wrigglers and small fry in caves and take them out for feeding when they feel there is enough safety. V. hartwegi are very shy and the male would temporarily abandon the territory when the threat is too large. Nevertheless as they fry grows the male takes bigger risks, in the last part we can see a male guiding the fry as the female was missing for some reason. Fry move very fast lead by the parents.
