Corydoras concolor: A Comprehensive Guide

Corydoras concolor, also known as the Camo Cory, is a fascinating freshwater fish cherished by aquarists for its unique appearance and peaceful nature. This guide covers everything you need to know about Corydoras concolor, from their natural distribution and habitat to their dietary needs and spawning practices.

Distribution and Habitat

Corydoras concolor is native to the freshwater rivers and streams of Venezuela, particularly in the Orinoco River basin. These fish are typically found in slow-moving waters with sandy or muddy substrates, often accompanied by leaf litter and aquatic vegetation.

Size and Appearance

Corydoras concolor are small, bottom-dwelling fish, growing to about 2.5 inches (6.5 cm) in length. They have a distinctive color pattern, with a camouflaged appearance featuring a blend of brown, black, and grey hues. This coloration helps them blend into their natural environment.

Water Parameters

Maintaining optimal water conditions is essential for the health of Corydoras concolor:

  • Temperature: 72-79°F (22-26°C)
  • pH: 6.0-7.5
  • Hardness: 2-15 dGH

These fish thrive in well-oxygenated water with moderate flow, mimicking their natural habitat.

Tank Mates

Corydoras concolor are peaceful and social fish, making them ideal for community tanks. Suitable tank mates include:

  • Tetras
  • Rasboras
  • Livebearers
  • Rainbowfish
  • Small peaceful cichlids

Avoid housing them with aggressive or overly large fish that might intimidate or harm them.


In the wild, Corydoras concolor are omnivores, feeding on a variety of invertebrates, plant matter, and detritus. In captivity, they thrive on a varied diet:

  • High-quality sinking pellets or wafers
  • Live or frozen foods such as bloodworms, brine shrimp, and daphnia
  • Blanched vegetables like peas and zucchini

A balanced diet ensures their vibrant coloration and overall health.


Corydoras concolor are active and social, typically found in groups. They exhibit fascinating behaviors, such as "summing" the substrate to find food particles. They are best kept in groups of at least six to promote natural behaviors and reduce stress.


Breeding Corydoras concolor in captivity is relatively straightforward, making them a favorite among aquarists. Key points include:

  1. Conditioning: Feed the breeding group a high-protein diet, including live and frozen foods, for several weeks.
  2. Breeding Tank: Set up a separate breeding tank with soft, slightly acidic water and a temperature around 77°F (25°C). Provide plenty of hiding spots and smooth surfaces for egg-laying.
  3. Spawning Process: Males will chase females, who lay adhesive eggs on surfaces such as plant leaves or aquarium glass. Remove the adults after spawning to prevent egg predation.
  4. Hatching: Eggs typically hatch within 3-5 days. Feed the fry infusoria or liquid fry food until they are large enough to consume baby brine shrimp.

  • They are peaceful and excellent for community tanks, contributing to a balanced aquarium ecosystem by cleaning up leftover food from the substrate.
  • Corydoras concolor are often seen performing synchronized swimming in groups, creating a fascinating display of natural behavior.
