Corydoras Panda

Description of Corydoras Panda


The fins of Corydoras Panda match the body in ground colour, upon close inspection being seen to be hyaline or translucent with coloured fin rays, with the dorsal fin being marked by a conspicuous black blotch that covers almost the entire fin area. The caudal peduncle is marked with a black band, this black band encircling the caudal peduncle from dorsal to ventral surface. The adipose fin of Corydoras Panda, supported by a small fin spine, sometimes contains black pigmentation. The pelvic fins are positioned upon the ventral surface of the fish, located some way behind the pectoral fins. The body color is white. The fins are the tan to bronze in color, but the dorsal fin is black. The fish possesses, in common with almost all Corydoras species, three pairs of barbels - one pair of maxillary barbels and two pairs of rictal barbels.

A fully mature adult specimen of this species attains a standard length of 55 millimetres (2.1 inches): this is the length attained by mature females, which grow larger than mature males, and also possess more rounded body outlines.

The proximity of the home rivers of Corydoras Panda to the Andes mountain range, and the replenishment of those rivers with meltwaters from Andean snows at higher altitudes, has led the fish to be adaptable to cooler temperatures than the norm for ‘tropical’ fishes - the temperature range of the fish is 16°C to 28°C, though the fish exhibits a marked preference for the cooler regions of this temperature spectrum, particularly in captivity.

Description of Corydoras Pygmaeus


Corydoras Pygmaeus, is a freshwater fish belonging to the Corydoradinae sub-family of the Callichthyidae family. It originates in inland waters in South America, and is found in the Madeira River basin in Brazil

The fish will grow in length up to 0.75 inches (2.1 centimeters) with females being larger than the males. It lives in a tropical climate in water with a 6.0 - 8.0 pH, a water hardness of 2 - 25 dGH, and a temperature range of 72 - 79°F (22 - 26°C). The body color is dirty white to beige and matches the color of the belly. The back is olive brown and dark brown to black stripe extends from the tip of the snout back to the caudal penuncle.

It feeds on worms, benthic crustaceans, insects, and plant matter. It lays eggs in dense vegetation and adults do not guard the eggs. The female holds 2-4 eggs between her pelvic fins, where the male fertilizes them for about 30 seconds. The pair repeats this process until about 100 eggs have been fertilized and attached.
