Common Name: CW027 Hi Fin Spotted Cory Catfish
Scientific Name: Corydoras cf. brevirostris
Other Names: CW027 Spotted Cory
The CW027 Hi Fin Spotted Cory Catfish is a rare and visually distinct Corydoras species, recognized for its high dorsal fin and spotted patterning along its body. This species closely resembles Corydoras brevirostris but is considered a separate variant due to its unique fin structure and markings. Like other Corydoras, it is a peaceful bottom-dweller that thrives in groups and contributes to a lively, active aquarium.
Habitat and Distribution:
Native to South America, specifically slow-moving tributaries and floodplain areas, CW027 inhabits soft, sandy-bottomed waters with leaf litter and submerged vegetation. These environments are warm, well-oxygenated, and slightly acidic to neutral.
Size and Lifespan:
This species grows to about 2.5-3 inches (6-7.5 cm). With proper care, it can live 8-10 years.
Diet and Behavior:
CW027 is an omnivore, feeding on small invertebrates, detritus, and plant matter in the wild. In captivity, their diet should include high-quality sinking pellets or wafers, frozen or live foods such as bloodworms, daphnia, and brine shrimp, and blanched vegetables like zucchini or spinach. They are peaceful and highly social, best kept in groups of at least five or more. They are active foragers, often seen sifting through the substrate and occasionally darting to the surface for air.
Breeding and Reproduction:
This species is an egg scatterer, with females laying eggs on smooth surfaces such as plant leaves, aquarium glass, or decorations. To encourage breeding, frequent water changes with slightly cooler water can simulate rainy season conditions, and broad-leaved plants or breeding mats should be provided. Adults do not guard their eggs, so removing the parents after spawning can improve fry survival. Eggs hatch in 3-5 days, and fry should be fed powdered fry food or newly hatched brine shrimp.
Aquarium Care and Tank Requirements:
A minimum of 20 gallons is recommended for a small group, with a larger tank preferred for a bigger school. Their ideal setup includes a soft sand substrate to protect their barbels, driftwood, leaf litter, and caves to mimic natural habitats, gentle filtration such as sponge or canister filters, low to moderate water flow, and dim to moderate lighting with floating plants to provide shade.
Ideal Tank Mates:
CW027 is a peaceful community fish that thrives with similarly sized and non-aggressive tank mates. Suitable companions include small peaceful tetras (Cardinal, Rummy Nose, Ember Tetras), dwarf cichlids (Apistogramma, Mikrogeophagus ramirezi), small rasboras and danios, other Corydoras species, and peaceful dwarf gouramis. Avoid aggressive fish that may outcompete them for food.
Difficulty Level:
Beginner to Intermediate. They are hardy but require stable water conditions and a group setting to thrive.
Water Parameters:
-
Temperature: 72-80°F (22-27°C)
-
pH: 6.0-7.5
-
General Hardness (GH): 2-12 dGH
-
Carbonate Hardness (KH): 2-8 dKH
-
Ammonia: 0 ppm
-
Nitrite: 0 ppm
-
Nitrate: <20 ppm (regular water changes required)
Additional Information:
- CW027 is a relatively new and uncommon species in the aquarium trade, making it highly desirable among Corydoras enthusiasts.
- Their high dorsal fin sets them apart from other similar species, adding to their unique appearance.
- They are best kept in groups, as solitary individuals may become stressed and exhibit less natural behavior.
The CW027 Hi Fin Spotted Cory Catfish is a peaceful, active, and visually interesting species that adds personality to any freshwater aquarium. With proper care, they make an excellent choice for both beginner and experienced aquarists looking to keep a rare and unique Corydoras species.
