False Spotted Corydoras

Corydoras leucomelas is a mid-sized Corydoras catfish known for its bold black eye mask and the dark blotch on its dorsal fin. Fine speckles scattered across its body catch the light at different angles, giving it a subtle, shimmering pattern. Hardy and naturally inclined to shoal, this species settles in well for the long term in a tank with enough floor space, roughly 90cm class. Watching it forage along the substrate alongside its shoalmates is endlessly engaging, making it a favorite among Corydoras enthusiasts.

Temperature
22〜26℃
Diet
Sinking dried foods, frozen bloodworm, Tubifex
Tank
A 90 x 30cm base of about 81 litres is the minimum. Use fine rounded sand and provide driftwood or plants as cover.
Water Temperature & Quality
22-26C. Use the FishBase wild range of pH 6.0-8.0 and 2-25dH as a guide.
Tank Mates
Peaceful and gregarious; keep at least 4-6. It mixes well with similarly sized peaceful species.
Diet & Feeding
A foraging omnivore. Feed sinking dried food plus frozen bloodworm and Tubifex, varying the diet.
Breeding & Spawning
Two or more males per female. After the females fill with eggs, carry out a 50-70 percent change with cooler water. Eggs go on glass, fine-leaved plants or mops and hatch in 3-4 days; fry need excellent water quality.

About False Spotted Corydoras

A mid-sized Corydoras with a striking black eye mask. Hardy and shoal-loving, well suited to long-term keeping in a 90cm-class tank for intermediate keepers.

7 things to know before welcoming a False Spotted Corydoras

  1. 1Best kept in a shoal

    Corydoras have a strong schooling instinct and tend to behave more calmly when kept in groups rather than alone. Watching them forage together along the substrate is one of the species' signature charms.

  2. 2Aim for 90cm-class floor space

    Adults reach about 4.5-5.5cm, a mid-size for Corydoras, and the group needs room to move around the tank floor. A 90cm-class tank is considered a good baseline for stable, long-term keeping.

  3. 3Choose soft substrate

    Corydoras use their barbels to probe the substrate while searching for food. Sharp-edged gravel can damage the barbels, so fine, rounded sand is a safer choice.

  4. 4Suited to intermediate keepers

    This species is manageable with basic water-quality knowledge, but it's generally recommended for keepers who already have some aquarium experience rather than as a first tropical fish.

  5. 5Enjoy individual mask variation

    The black eye mask and dorsal-fin blotch vary slightly in shade and shape between individuals, and the body speckles shift in appearance depending on the light angle, making it fun to compare fish side by side.

  6. 6Pair with peaceful tankmates

    Temperamentally peaceful, it rarely bothers other fish and pairs well with similarly calm small-to-mid-sized species. That said, Corydoras can startle easily, so sudden noise or vibration near the tank should be avoided.

  7. 7Cycle the tank before arrival

    Because it constantly probes the substrate, it can be sensitive to sudden water-quality shifts or accumulated waste. Be sure the tank's filtration cycle is fully established and the water parameters are stable before bringing the fish home.
