Pterophyllum scalare is a species of fresh wáter, native to the Tapajoz River, tributary of the Amazon, as well as numerous streams in the northern part of Brazil, with great economic potential that places it among the most demanded freshwater ornamental species in the market for its exotic angel shaped morphology; In addition, it produces translucent oocytes, allowing easy observation of embryonic development to study the chronological process of the morphogenesis of a new organism (larvae). However, we can determine that there are few studies that clearly identify the different stages in the embryonic process of the scalar fish. The present study tries to describe to provide an approximation of the embryological process of the species, to follow up during a period of 48 hours, to contemplate the stages of cell division, until the larval formation with yolk sac, an optimal tropical temperature of 28 ± 2 ° C; which was developed in the Ornamental Fish Laboratory of the University of Nariño, Pasto, Nariño, Colombia.
