Evelyn’s Cory

The Evelyn’s Cory, scientifically known as Corydoras evelynae, is a small, peaceful species of catfish native to the Amazon Basin in Brazil. It is a charming addition to aquariums, prized for its subtle patterning and lively shoaling behavior.

Adult Evelyn’s Corys typically reach about 1.5 to 2 inches (4 to 5 cm) in length. Their body is pale with several thin, dark horizontal lines running along the flanks, a dark stripe through the eye, and a squarish blotch beneath the dorsal fin. The pattern gives them a unique look compared to other Corydoras species.

A tank of at least 15 to 20 gallons is suitable for a small group. As with all Corydoras, they are social and should be kept in groups of six or more. A soft sand substrate is ideal, allowing them to sift naturally without damaging their barbels. Driftwood, smooth rocks, leaf litter, and dense plants help recreate their natural environment and provide cover.

Water parameters should include a temperature of 72 to 79°F (22 to 26°C), a pH between 6.0 and 8.0, and soft to moderately hard water. Regular partial water changes and good filtration are important for their health.

Feeding Corydoras evelynae is straightforward. They accept sinking pellets and wafers as a staple diet, and they thrive when offered live or frozen foods such as daphnia, bloodworms, and brine shrimp.

Evelyn’s Corys are peaceful bottom dwellers that pair well with other small, gentle community fish such as tetras, rasboras, pencilfish, and dwarf cichlids. Avoid large or aggressive species.

Breeding follows the typical Corydoras pattern. The female carries eggs between her pelvic fins for fertilization before placing them on plants, glass, or décor. Adults provide no care and may eat the eggs, so a separate breeding tank or protective planting helps fry survival. Fry should be fed infusoria or baby brine shrimp once free-swimming.

Corydoras evelynae (Evelyn’s Cory) is a delightful and understated catfish that brings charm, activity, and group behavior to peaceful community aquariums.
