Corydoras Melanotaenia - Wild 4cm

Corydoras Melanotaenia

Wild-caught corydoras always have a certain authenticity to them that really appeals to dedicated catfish keepers, and Corydoras melanotaenia is no exception. This elegant species is a fantastic choice for aquarists who enjoy more unusual bottom-dwelling fish and want something beyond the standard bronze or panda cory. Their natural patterning, active shoaling behaviour, and constant substrate sifting make them a rewarding species to keep in planted community aquariums.

Corydoras melanotaenia displays a clean silver to pale cream base colour with a striking dark horizontal stripe that runs cleanly from the snout through the eye and down the length of the body toward the tail. This bold lateral stripe is what makes the species so visually appealing, especially when kept in groups over lighter sand substrates. The fins are mostly translucent, sometimes carrying a soft golden or smoky tint depending on the individual and lighting. Like most corydoras, their rounded underside and downward-facing barbels are perfectly adapted for sifting through the substrate in search of food, and in groups, they are constantly active and entertaining to watch.

Sexing this species is relatively straightforward once mature, with females becoming slightly larger and fuller-bodied than males, especially when viewed from above. Breeding follows the classic corydoras spawning method where the pair enters the well-known "T-position." The female then deposits adhesive eggs on aquarium glass, plants, or décor. In cooler water changes or storm-like pressure shifts, breeding behaviour is often triggered quite reliably.

Tank Recommendations for your Corydoras Melanotaenia

These corydoras are highly social and should always be kept in groups of 5–6 or more, with larger groups bringing out much more natural shoaling behaviour. A minimum aquarium size of 60 litres is recommended.

A soft sandy substrate is strongly preferred as it protects their barbels and allows natural foraging behaviour. Driftwood, leaf litter, plants, and shaded resting areas all help them feel secure. As a wild-caught species, they particularly appreciate stable water quality and mature aquariums.

Suitable Tank Buddies

These fish are extremely peaceful and excellent for planted community tanks.

Usually Compatible

Tetras, rasboras, dwarf cichlids, and peaceful livebearers.

Sometimes Compatible

Shrimp and nano fish.

Rarely Compatible

Large aggressive cichlids or predatory fish.

Feeding your Corydoras Melanotaenia

These corydoras are very easy to feed and spend most of their time actively searching the substrate for food. Sinking foods are always best so they can feed naturally from the bottom. The ideal diet would be a quality sinking pellet or wafer, supplemented with frozen bloodworms, blackworms, or baby brine shrimp, which also helps condition them for breeding.
