Corydoras arcuatus

 

Overview:

    Like most of the members of the species the skunk cory is hardy and a great community scavenger. A little more sensitive to water conditions than most, your frequent partial water changes will benefit it.

Distribution

    Found throughout the Amazon river basin in Ecuador, Peru and Brazil.

General Body Form

    Typical for the genus, The lateral armor consists of 22 to 24 upper and 20 to 22 lower bony plates. The upper jaw barbels extend almost to the gill slits. They can reach a length of about two inches.

Coloration

    The most noticeable characteristic of the skunk cory is the broad dark or Black stripe that starts near the nose and curves under the Dorsal fin and runs down the body until the start of the tail fin. At the tail it bends and continues down to the lower section of the tail. The central area of each side is a pale yellow or green color and the belly is white. The tail fin has small black dots and the other fins are basically colorless.

Maintenance

    1. Most species of

Corydoras

     will tolerate a wide range of variations in temperature, pH and hardness. As a general rule they will do fine if kept within the following ranges, Temperature: 72°F to 79°F , pH:6.2 to 7.8 and a dH of 4 to 25. The skunk cory is a little prone to bacterial infections so good filtration and proper maintenance are needed. The tank can be decorated with driftwood and a few live plants, soft sandy substrate is essential to prevent damage to the barbals. The water should be well aerated and changed at regular intervals. The Armored catfish are Omnivorous and should be fed a varied diet. Do not simply rely on uneaten food on the bottom as there only source of food.

Breeding

    One of the harder of the species to breed, Sexually mature specimens are easy to tell apart, the females have a more stout body and are less colorful. The males have a larger and more pointed Dorsal fin. Easier to sex when viewed from above. You should have a ratio of two males to each female. Courtship consists of the male touching the female with his snout and then the female will swim constantly around cleaning rocks or plant leaves in the tank. Then a male will grab the females barbals and twist his body into hers and she will release her egg pouches at the same time as the male sperm. This is repeated several times with the female taking the egg pouches and placing them at various locations throughout the tank. After spawning you can remove the parents from the tank. The eggs will hatch in about five to eight days and the young are not hard to raise and can be fed fine flake food or newly hatched brine shrimp (fresh or frozen). Growth is fairly rapid given proper conditions.
