Corydoras venezuelanus

The peaceful and endearing Corydoras venezuelanus freshwater fish brings vibrancy to any aquarium. Aquarium enthusiasts love these catfish because of their lively coloring and playful nature. They are perfect for both novice and seasoned fish keepers because they are small, low maintenance, and thrive in a communal tank.

Due to their gregarious nature, these bottom-dwelling fish are frequently observed in groups as they rummage through the substrate in search of food. By scavenging for leftover food, Corydoras venezuelanus contribute to the cleanliness of the aquarium in addition to being entertaining to watch.

Corydoras venezuelanus are hardy and amiable creatures that can add a lot of charm to your aquatic setting. They are a flexible option for community tanks since they get along well with many other peaceful fish species.

Habitat and habitat

South America, the waters of Venezuela.

This species is common in the lower reaches of rivers and streams in the northern Venezuelan states of Miranda, Aragua, and Carabobo, as well as in the Rio Tuy and Lake Valencia basins. Additionally, it is present in the neighboring Rio Chirgua and other Orinoco rivers and streams.

This species never occurs on the plains; it prefers colder waters.

Cool, clear water with a neutral pH and moderate hardness is the natural habitat. The substrate of the majority of these streams is typical of high mountain streams, consisting of gravel and rounded rocks, and the water flows quickly.

The popular freshwater catfish Corydoras venezuelanus is prized for its unique bronze-orange color, calm disposition, and hardy nature. This species is abundant in community aquariums, where it scavenges leftover food and debris, keeping the tank clean in the process. These bottom-dwelling fish bring vibrancy and charm to any home aquarium. They are also easy to care for and active in groups.

Description

Possesses a noticeable iridescent reddish-brown patch on the back of the head and a sizable oval green or black patch covering the shoulder girdle.

Commercially bred specimens can have balloon-shaped bodies, but they may have shorter bodies than their wild counterparts.

Size:

Adult fish typically have a maximum standard size of 55–60 mm.

Behavior and compatibility

Called a social species, it is peaceful and gregarious, and should be kept in groups of four or more to fully display its typical behavior.

Takes up residence on the aquarium’s lower level.

A tranquil fish, you should avoid having aggressive neighbors and instead select fish that are similar in size and behavior (haracins and the like) as your neighbors.

Similar to many labyrinth fish, the catfish can breathe atmospheric air and frequently rushes to the water’s surface when there is not enough oxygen present. Fish in this genus require access to the water’s surface and have additional breathing through their intestines, just like other members of the family.

Aquarium

A 50-liter capacity is needed, along with filtration and aeration to produce a weak water current that mimics natural conditions. Corydoras are primarily found in small streams, and while rounded gravel works just fine, fine sand is the preferred substrate.

The rest of the décor is mostly up to personal taste; you can add some tiny stones and snags. Catfish will use the live aquarium plants to mimic their natural habitat and to make their homes.

Prefers lighting that is diffused.

Water parameters:

Temperature range: 21–27°C pH range: 6.0–8.0 Hardness range: 7–20 dH

Maintaining optimal water quality and routinely cleaning the substrate are essential; any deviation from these parameters will negatively impact the fish’s health.

Nutrition

They are omnivores, so feeding them is easy. They will eat any sinking dry food as well as live and frozen foods like bloodworms and tubifex.

When kept in an aquarium, fish will maintain their best condition with a varied diet.

Sexual Dimorphism

Although females typically grow to larger sizes and mature individuals have a noticeably rounder and wider body, sexual differences are not strongly expressed.

By the age of eight to twelve months.

Breeding

It is best to plant a group of 1.5-year-old fish (4-6 males and 2-3 females or 2-3 males and 1 female) for spawning. The fish should be kept apart for a week prior to this and fed a lot of different kinds of food.

Airlift spawning, as well as general spawning in a small aquarium equipped with an air filter.

Low air pressure is another factor that promotes spawning, as is the regular addition of cool, fresh water.

Men start to chase after the restless female swimmers. The female then lays multiple eggs in fins folded like a ladle and swims through this cloud after one of them stands sideways in front of her head and releases milt. Up to 300 eggs are laid by the female on leaves and other hard surfaces. This can take anywhere from a few hours to three days, and it is repeated multiple times. Because the female can eat the eggs, it is advised to feed the fish heavily at this time to prevent starvation.

Following spawning, the fish are taken out or the substrate containing the eggs is moved to an incubator; if the eggs are laid on the aquarium’s glass, they must be carefully scraped off using a razor.

The fry swim the day after they have been incubated for three to six days. Food for starters is live dust.

Fry learn to color like adults very early on.

An excellent addition to any freshwater aquarium is Corydoras venezuelanus. By scavenging for leftover food, these calm bottom-dwellers are not only endearing but also aid in maintaining the cleanliness of the tank. They are a pleasure to watch, especially when kept in groups, due to their gregarious and lively nature.

These catfish are suitable for both novice and seasoned aquarists due to their adaptability and comparatively low maintenance requirements. To help them feel at home, make sure they have lots of hiding places and a soft substrate.

The Venezuelan Cory is a fantastic option if you want to give your aquarium some life or just enjoy the beauty of corydoras. They will flourish and give your tank a lot of character if given the right care.
