Sterba's armored catfish ( Corydoras sterbai ), named after the ichthyologist Günther Sterba , also known as orange-fin, gold-fin or yellow-fin catfish, is an armored catfish native to Brazil , in the upper reaches of the Rio Guaporé . Because of its attractive drawing, it is often kept as an ornamental fish in aquariums.
The armored catfish, which is quite large with a total length of eight centimeters, is relatively high back compared to other Corydoras species. The head and back are light to dark brown in color and covered with yellowish dots. Towards the caudal fin, the sides of the body are striped brown and yellowish. The belly is white to pink in color. The fin color, suggested by some common names, refers to the first ray of the pectoral fins, which is yellow to bright orange.
During the spawning season, mating takes place every five to seven days, in which only one or two very sticky eggs are attached to the undersides of the leaves of large-leaved aquatic plants. A female produces around 30 eggs in one spawning period. The larvae hatch after about four days.
Fin formula : dorsal 1/8, anal 1/7, pectoral 1/10, ventral 1/6.
