Corydoras rabauti provides beauty and ease of care for both novice and experienced aquarists. With a little knowledge of their requirements and the provision of an appropriate habitat, you can watch these delightful fish bring some joy to your aquarium.

Habitat and range

South America: River basins of the Negro, Solimões, and Upper Amazon.

The majority of records come from the Javari River, an Amazonian tributary that flows into the main Amazon at Tres Fronteiras, the point where the borders of Brazil, Peru, and Colombia converge. The Javari River forms the border between Brazil and Peru for the majority of its length.

Therefore, it appears likely that C. rabauti is found in Brazil, Peru, and possibly Colombia, though its exact distribution is unknown.

It lives in tributaries with murky, acidic water that is rich in tannic and organic compounds derived from the decay of driftwood and leaves. It also lives in areas of land that are flooded and small lakes.

For both novice and seasoned aquarium enthusiasts, Corydoras rabauti is a delightful and resilient species of catfish. This fish, which is well-known for its striking pattern and calm demeanor, brings something special to any tank and aids in maintaining clean substrate. Corydoras rabauti thrives and contributes to a balanced aquatic environment when its care requirements—such as ideal tank conditions and compatible tank mates—are understood.

Description

Fish that are young and adults have very different colors. Young catfish have an emerald spot that almost completely covers their body near the tail, giving them a striking appearance.

They become rusty (brick-orange, beige, or light brown) as they get older. Starting from the head and ending at the tail is a broad, dark stripe. Every fin is see-through.

Size:

Size maximum: 55–60 mm.

Behavior and compatibility

Aquarists adore this easy-care fish because it’s lively, amiable, and inquisitive.

Since these are schooling fish, they should be kept in groups of four or more.

Pleasant and calm, with a preference to remain at the bottom. Compatible with all small, non-aggressive species. Rainbowfish, rasboras, characins, dwarf cichlids, tetras, labyrinth, and other small catfish species make excellent neighbors.

Aquarium

Aquariums with a minimum base size of 90*30 cm are advised.

Like with all Cory, the soil must be soft. Sand is the ideal substrate, but small, rounded gravel will also work. The rest of the décor is mostly up to personal preference, but to keep the fish safe, there should be some shelters in the form of stone grottoes with snags.

Additionally, adding plants is a good idea, but they should be placed so that there is room on the bottom, where these catfish spend the majority of their time. They like soft lighting, ideally with a diffused glow.

The fish must have access to the water’s surface, where they periodically come to take in oxygen.

Water parameters:

In the range of 22 to 27 °C pH range: 5.5–7.2 Hardness: between 2 and 15 ° dH

A third of the population performs weekly water changes, and aeration and filtration are preferred.

Feeding

Tiny invertebrates and plant matter make up the diet of creatures found in nature.

All kinds of food are accepted in the aquarium. The best kind of food for bottom fish is sinking food, such as granules and tablets. You should occasionally feed live and frozen food, such as daphnia, brine shrimp, bloodworms, and tubifex.

A varied diet will guarantee that the fish are at their best.

Sexual Dimorphism

The larger size and more rounded abdominal line of females are particularly apparent when the eggs are developing.

Breeding

A 20-liter tiny spawning tank is required. You can use fine sand instead of soil, but it’s not required. If the filter is mechanical, you must cover it with a sponge to prevent the fry from being drawn into it. Alternatively, you can use an airlift or air filter. As plants, a few bushes of Java moss will work.

The spawning aquarium’s water parameters are 24–25 °C, pH 6.5, and dGH up to 6.

The breeders should be fed a variety of foods during the pre-spawning period. To encourage spawning, you should start replacing between 50 and 70 percent of the water every day once the female’s abdomen becomes rounded. When a male is ready to spawn, he becomes more active and follows the female.

The breeders must be added to the spawning tank in the evening, with three to five males for every female. Fish typically spawn in the morning in the brightest area, which is frequently on the side glass. The female lays two to four eggs at a time, each no bigger than two millimeters in diameter. She retains the eggs between her ventral fins, where the male fertilizes them for around thirty seconds. The female swims to a suitable location and attaches the eggs only then. This procedure is repeated by the couple until roughly 100 eggs are attached and fertilized.

After spawning, the producers are removed right away because the temperature in the spawning tank rises by two to three degrees and the adult fish eat the eggs. The eggs are shielded from fungal infection by the addition of methylene blue to the water. You can throw freshwater shrimp into the spawning tank, where they will consume the bad eggs and leave the good ones behind.

On the third to fifth day after hatching, the larvae consume the yolk for one day. After that, microworms and brine shrimp nauplii should be given to the fry.

By the time they are 8–10 weeks old, the fry have developed the color typical of mature fish.

A charming addition to any aquarium is Corydoras rabauti. This catfish, which has a striking appearance and a calm demeanor, adds both beauty and personality to your tank. It is a favorite among aquarists because of its unique markings and lively behavior. Corydoras rabauti might be the ideal option if you want to give your aquatic setup a dash of elegance and intrigue.

Because they require little maintenance, these fish are perfect for both novice and seasoned hobbyists. They do best in well-kept tanks with lots of hiding places and a supple substrate. They will bring life to your aquarium with their vivid colors and entertaining antics in the correct setting.

All things considered, Corydoras rabauti is a charming species that raises the diversity and aesthetic appeal of any freshwater aquarium. If you give them the right attention and space, you’ll be able to enjoy their company and lively presence for many years to come. Cheers to many years of fishkeeping!
