  • Corydoras latus is a popular freshwater fish species native to South America known for its unique characteristics and features.
  • These small catfish belong to the Callichthyidae family and are recognized for their wide and broad body, with distinct markings and coloration patterns.
  • Corydoras latus typically grows up to 2 inches and has a lifespan of 5 to 8 years or longer.

Species Overview

Corydoras latus, also known as the Wide Cory or Bred Pansermalle (Denmark), belongs to the scientific lineage 8 sub-clade 3 of the Corydoras genus. It is a member of the Callichthyidae family. The name “Corydoras” refers to its helmet-like appearance, while “latus” describes its wide and broad body.

This species is native to South America, primarily found in the Beni River basin in Bolivia. It can also be found in other regions such as the Amazon, Middle Amazon (Solimoes), Madeira, and Beni.

Describing its physical characteristics, Corydoras latus was first described by ichthyologist Nathan Everett Pearson in 1924 based on a single specimen from Lago Rogagua or its surroundings in Bolivia. The holotype exhibited a high, large, short-snouted body with uniform blackish coloration.

Corydoras latus typically grows up to a size of about 52mm or 2″ SL (Standard Length). This species has a slow growth rate and can live for approximately 5 to 8 years or even longer.

In terms of appearance, Corydoras latus showcases distinct markings and coloration patterns that make it visually appealing. These features vary among individuals but often include dark spots or stripes on a lighter background color. Such markings serve as camouflage and help them blend into their natural environment.

As for specific adaptations or behaviors displayed by this species, they are known for their bottom-dwelling nature and their ability to sift through sand or substrate using their barbels. They have an omnivorous diet consisting of small insects, crustaceans, plant matter, and detritus.

Habitat & Tank Conditions

To ensure the well-being of Corydoras latus, it is essential to provide them with an appropriate habitat and tank conditions. Here are some key factors to consider:

Tank Size & Set Up

Corydoras latus requires a minimum tank size of 20 gallons (75 liters) to thrive comfortably. It’s important to set up the tank properly to mimic their natural habitat.

  • The tank should have a cover to prevent any accidental escapes as these fish are known for their jumping abilities.
  • Avoid filling the tank all the way to the top, as Corydoras latus may swim near the surface and need some breathing space.

Water Parameters

Maintaining suitable water parameters is crucial for the health of Corydoras latus. Here are the preferred ranges:

  • pH Range: 6.0 – 8.0
  • Temperature Range: 22°C – 26°C
  • Hardness Levels: Moderate hardness is ideal for these fish.

It’s recommended to use a reliable thermometer and test kits to monitor and maintain stable water conditions in the aquarium.

Substrate & Decor

Choosing the right substrate is important for Corydoras latus, as they are bottom-dwelling fish with a burrowing behavior. Opt for sand or fine gravel that won’t harm their delicate barbels while they search for food.

Sandy substrates are excellent for these bottom dwelling species.

In addition to suitable substrate, providing hiding spots such as caves or plants can create a comfortable environment for these fish. They appreciate having places where they can retreat when feeling stressed or threatened.

By creating an environment that closely resembles their natural habitat, you can ensure that your Corydoras latus will thrive and exhibit their natural behaviors in your aquarium.

Tankmates & Temperament

It’s important to consider their peaceful temperament and social behavior. These little catfish are generally friendly and get along well with other peaceful community fish.

Compatible Tank Mates

Corydoras latus can coexist peacefully with a variety of tankmates, including:

  • Tetras: Neon tetras, ember tetras, and cardinal tetras make great companions for Corydoras latus.
  • Guppies: These colorful and lively fish add a vibrant touch to the aquarium while getting along well with the corydoras.

Tank Mates to Avoid

It’s best to avoid housing Corydoras latus with aggressive or larger species that may intimidate or harm them. Some examples of tank mates to avoid include:

  • Cichlids: Aggressive cichlids may see the smaller corydoras as potential prey or competition.
  • Barbs: Certain barb species can be nippy and may stress out the peaceful corydoras.

Corydoras latus prefer being kept in groups, so it’s recommended to have at least six individuals in the tank. This promotes their natural social behavior and makes them feel more secure.

Corydoras latus Care

Corydoras latus, also known as the Latus Cory, requires proper care to thrive in an aquarium environment. Here are some essential tips for their care:

Care Recommendations

To ensure optimal water quality for their well-being, regular maintenance tasks like partial water changes are necessary. These tasks help remove toxins and maintain a clean and healthy environment for the fish.


When handling Corydoras latus, it is important to exercise caution due to their hardened pectoral spines that can pierce human skin. Always handle them with care and avoid any unnecessary contact that may cause injury.

During transportation, it is advisable to use a plastic container instead of a net. Nets can entangle their spines, leading to potential harm or stress for the fish.

It’s worth noting that these fish are sensitive to salt. Adding salt to the tank can be harmful to their health, so it’s best to avoid using salt altogether.

Diet & Nutrition

Corydoras latus are omnivorous creatures and have a varied diet in the wild. In captivity, it is recommended to provide them with high-quality sinking pellets as their staple food source. Supplementing their diet with frozen foods such as bloodworms or brine shrimp can provide them with essential nutrients.

These fish have a habit of eating anything that sinks to the bottom of the tank. They readily accept dried, live, and frozen foods alike.

Common Diseases & Prevention

Monitoring the health of your Corydoras latus is crucial for their well-being. It is important to observe any signs of illness promptly and take appropriate action if needed.

Regularly observing their behavior and feeding habits can help identify any abnormalities early on. This will allow you to address potential issues before they escalate into more serious health problems.

Breeding the Corydoras latus

The breeding behavior of Corydoras latus is quite fascinating. These catfish prefer to spawn in pairs or small groups, creating a social dynamic during the breeding process.

Recommended Tank Set Up

To encourage breeding, it’s important to create specific conditions in the tank. Corydoras latus thrive in slightly cooler water temperatures, typically around 72-76°F (22-24°C). Increasing water flow with a gentle current can help induce spawning behavior.

Breeding Process

Females play a crucial role by laying adhesive eggs on various surfaces within the tank. The males then fertilize these eggs externally. It’s common for Corydoras latus to lay their eggs on broad-leaved plants or even flat rocks.

During this process, it’s essential to provide suitable hiding spots and vegetation for the adults to feel secure and comfortable. This encourages successful egg-laying and fertilization.

Fry Care

If you’re interested in raising fry (baby fish), there are a few things to consider. After spawning, it’s best to remove the adult fish from the tank since they may eat their own eggs or newly hatched fry.

To care for the fry, provide them with ample hiding places such as dense vegetation or specialized breeding traps. Feeding them small-sized food particles like crushed flakes or baby brine shrimp will ensure proper nutrition as they grow.

It’s important to maintain excellent water quality during this stage as well. Regular water changes and monitoring parameters like ammonia and nitrite levels are crucial for their survival.

Breeding Corydoras latus can be an exciting endeavor for aquarium enthusiasts who want to witness the natural behaviors of these beautiful catfish firsthand.
