Corydoras Ornatus 4.5cm

Corydoras Ornatus

The Corydoras ornatus is a beautifully patterned and rare corydoras species in Australia, offering a more natural, refined aesthetic that fits perfectly into Amazonian biotope aquariums and planted community tanks. Its elegant patterning, peaceful temperament, and hardy nature make it a fantastic choice for collectors or aquarists who want something that stands out without being overly flashy. The Neon Green Stripe variety is both captivating and easy to care for.

These fish are incredibly bright, with their neon-green reflective stripe across the top of their bodies. When light catches it just right, the stripe glows with a metallic sheen, giving the fish an almost bioluminescent appearance in darker, heavily planted tanks. They maintain the classic corydoras shape and behaviour, foraging constantly and moving in small groups along the bottom, keeping the substrate clean and entertaining to watch.

Neon Green Stripe corydoras are best kept in groups of six or more to encourage natural schooling behaviour and reduce stress. These bottom dwellers constantly sift through the substrate for food, which also helps maintain a clean and well-oxygenated tank floor. Breeding these corydoras in captivity is possible but rarely documented. Like most Corydoras, they are egg scatterers. Females are generally rounder-bodied when mature, and a slight drop in temperature after a high-protein feeding routine can stimulate spawning. Providing soft, tannin-stained water, dim lighting, and dense vegetation can help replicate their natural breeding conditions.

Tank Recommendations for Your Corydoras Neon Green Stripe

As Green Stripe cories reach around 6 cm as adults, it is best to keep them in an aquarium with a minimum size of around 60 litres. A larger aquarium will always be better due to their active behaviour, and it also allows for the space to keep other tank mates.

A sand substrate is best, as coarser substrates like gravel often result in corydoras damaging their barbels. The Green Stripe cory would look best against a darker substrate to really highlight the metallic colour of this fish. They will also love plants in the aquarium and places for cover through the addition of driftwood.

Suitable Tank Buddies

The Neon Green Stripe corydora is an incredibly peaceful fish that can be kept with a massive range of community aquarium species. They do not display any aggression, even when breeding, and make for a perfect addition, even with sensitive or shy fish. The only factor that should be considered is that corydoras are almost exclusively bottom-dwelling fish, which means that any super active or large top-dwelling fish may outcompete them for food.

Usually Compatible

Community fish such as rams, tetras, angelfish, discus, rainbowfish, and many more.

Sometimes Compatible

Larger peaceful South American cichlids such as uaru, severums, and other fish which may outcompete them, as they are mostly bottom-dwelling fish.

Rarely Compatible

Large and aggressive species such as oscars, which may prey on the corydoras. This is especially important, as corydoras have spines on their pectoral fins like many catfish; this can result in both the corydora and the predator fish's death.

Feeding Your Corydoras Neon Green Stripe

Just like any other corydoras, these fish are very easy to feed. They will take a wide range of pellets, flakes, and frozen foods. Like any fish, they should be fed a varied diet with a mix of different foods. The ideal diet would be a good-quality micro slow-sinking pellet or crushed flake, supplemented with frozen bloodworms and even live baby brine shrimp or microworms.
