Among Corydoras, Paleatus is one of the most popular species, which is often chosen for an aquarium. These catfishes are a bottom inhabitant and grow in the length of no more than 7.5 cm, while females are slightly larger than males.

The name of the fish comes from three Latin words:

  • “Cory” – a helmet;
  • “Doras” – skin;
  • Palea is ashes.

The integument of Corydoras paleatus has bony plates that form a kind of carapace. The body color can be either pale green with an olive tint or blue with a blue tint.

You may also meet representatives with golden or white scales. Such subspecies were derived artificially. There are black spots on the body, on the back they are larger. The fins are transparent and also have small dark specks.

Like all catfish, the Paleatus also has a pair of mustaches on its upper jaw. Their main function is to search for food at the bottom of the reservoir.

Life expectancy depends on the temperature of the water. The warmer it is, the sooner metabolism occurs, and the sooner the fish ages. On average Corydoras Palateus fish live no more than 3-5 years.

Corydoras Paleatus Compatibility

Of course, Paleatus will not be the only inhabitants of the aquarium. Although the catfish is speckled as a whole, a peaceful fish, nevertheless it will not be able to get along with any or all the species.

The most successful tank mates for this catfish will be :

Corydoras Paleatus can get along well with eels, crab, or shrimp. These Catfish are completely incompatible with Oscar Fish, Cichlids, and Goldfish.

For catfish to live in the aquarium for as long as possible, it is not recommended to choose fishes who prefer warm water, as well as predators and other large species, as cohabitants.

Corydoras Paleatus Aquarium Care

Corydoras Paleatus prefer cool water, the temperature of which should not exceed + 22 ° C. It is not critical if the water is several degrees warmer. Aeration should be moderate. A periodic water change will be required, at least once a week.

If not enough pure water is added, the nitrates and decomposition products accumulated in the water can adversely affect the general condition of the fish.

Optimal conditions are medium aeration and a neutral environment (pH 7.0 ). You will need to acquire various snags or special artificial houses that will serve as a shelter for the shell.

Aquarium Decoration

It should be borne in mind that the scenery should not have sharp protrusions so that the fish does not hurt themselves about them.

As a substrate, river sand or gravel, the diameter of which will not exceed 5 mm, is ideal. This requirement arises from the extremely sensitive catfish mustache.

Many experienced aquarists advise beginners to purchase bottom filters that will purify water and also saturate it with oxygen.

If this filter is not installed, you will need to monitor the behavior of the fish. In case when the Paleatus begins to swim to the surface to gain air, it will be necessary to replace the water as soon as possible.

Since catfish is a benthic species, food that floats on the surface of the water is not suitable for it. For this, special granules or tablets should be purchased at pet stores that sink and sink to the bottom.

Corydoras Paleatus can eat both dry and live food. It should be remembered that an integral component of their diet is plant food.


As with most other fish, males have a brighter color than females. In this case, the females are slightly larger than their partners. Therefore, it is not difficult for even a novice aquarist to distinguish between males and females.

To breed Corydoras Paleatus at home, you will need to keep one female and several males (two or three are enough) in a separate aquarium. The water in the tank must be fresh and contain a large amount of dissolved oxygen, so you need to install an aerator.

For successful mating, it is necessary to reduce the water temperature by 2−3 degrees. It is these conditions that mimic natural conditions: catfish breed in the rainy season.

It is recommended to feed fish during this period with live food, which is rich in protein. The best option for Corydoras Paleatus is artemia, bloodworm, or tubule.

When the female is ready for mating, her abdomen turns red. Fish become more active, which is manifested in the marriage dance. In this case, the partner begins to “tickle” the fish. Then the male releases seminal fluid, and the female swallows it.


After the female lays eggs on any surface (leaves of aquatic plants, stones, a filter, or glass), she inseminates her. This process can last up to one hour. Corydoras Paleatus can lay 200 to 400 yellow eggs. After spawning, it is recommended to remove the male fish so that they do not eat their offspring.

Within a week, fry hatch from the eggs, which need to be fed with ciliates. Artemia or nauplius is suitable for young animals as food. Within six months, the fish grow by 6 cm (about one per month). If you create in the aquarium all the conditions for the life of Corydoras Paleatus, the fish will live up to 8 years.

Shell Disease

Like any other aquarium fish, catfish are prone to fungal and bacterial diseases. If the disease is detected on time, then the treatment will be successful, and the Corydoras Paleatus will live for a long time.

It should be remembered that adding salt to the aquarium is not suitable as a treatment for Corydoras Paleatus, as these fish cannot tolerate it.

If any deviations in the behavior of the catfish or changes in appearance (dull color, deformation of the fins, the appearance of plaque) were noticed, it is recommended to put Paleatus in a separate aquarium to protect other fish from infection.

Speckled catfish is one of those species that is ideal for a beginner aquarist. The maintenance of the corridor is not difficult and does not require much effort.
