Peppered Corydoras (Corydoras Paleatus) Fish Species Profile

The peppered Corydoras is one of the more popular types of Corydoras because it is very hardy, resistant and adapts to a wide range of water parameters, making this an ideal candidate for a beginner aquarist and the community tank.

These Corydoras are small, good looking catfish and they can be be found in a variety of colours and patterning, depending on where they originated.

Their body is relatively stocky and covered with two rows of bony plates, as are their heads. It is olive-tan and displays dark green to black markings with each individual being slightly different. Their fins are pale; their dorsal fin has a dark patch on the first few rays, the caudal fin has several fine spots and the adipose fin sports a spot on the upper tip. Overall they are essentially bronze with dark patches and specks.

On the upper jaw are two pairs of barbels, which help the fish to scour through the substrate for food. These species have articulated eyes allowing them to tilt their eyes up and down without having to move their head.

There is an albino variety of this species, but they tend to be very sensitive to water conditions, lighting and medicines, so they are quite challenging to keep.

Origins

Peppered Corydoras are native to Argentina, the Parana River and the Rio de la Plata in Brazil, Paraguay, Suriname, and Uruguay in South America.

They inhabit slow-moving almost still waters such as marshes, ponds, streams, lakes and rivers that are clear and shallow with a soft sandy substrate where they can forage for food.

Diet

The Peppered Corydoras is not hard to feed at all. They will commonly eat all kinds of live and flake foods. To keep the right balance, give them high-quality flake foods or sinking pellets every day as well as the occasional algae wafer and Feed them frozen, freeze-dried or live food, such as artemia, blood worms, or daphnia as a treat.

Sexing the Peppered Corydoras

It is easy to determine the different sexes of the Peppered Corydoras. Females are usually larger than males and more rounded in the belly. When viewed from above the difference is more prominent, as the female is much broader than the male. The males have a larger dorsal and pectoral fins, and their anal fin is more pointed than the females. Males are often more vibrant in colour than females.

Breeding the Peppered Corydoras

It is relatively easy to breed the Peppered Corydoras in the home aquarium.

You will know when the fish are ready to spawn as the female will increment discernibly in size and usually become more active, and the female's stomach and the first ray of the pectoral fin will display a reddish colour. This is the point where you will need to carry out a water change using water that is colder than the temperature in the tank this will make the fish believe it is the rainy season and hopefully induce spawning. Now you should select your best sized and coloured pair and place them in a separate spawning tank that has plenty of plants or surfaces that the female may place her eggs upon. This way, there is less risk of other fish as well as the parents eating the eggs.

The male will display a shivering motion during the mating ritual, and he will swim over the back of the female touching her with his barbels, he will then eventually take up the T position with his body placing it at a right angle towards the female's nose. This position triggers the release of milt as well as a small number of eggs that she will grip between her pelvic fins.

When all the eggs have been fertilized, the pair will go their separate ways. The female will then deposit the sticky eggs on a surface that she has already chosen and cleaned; this may be on a plant, glass, or filter tubes.

Once this process has taken place, it will then continue until the female has run out of eggs which usually takes a few hours, and she can lay up to 300 eggs. Now the parents should be removed from the tank, so they do not consume the eggs.

The eggs will usually hatch around four to six days later, and the small fry should be fed with infusoria or equivalent.
