Get ready to add some personality to your aquarium with the lively and fun-loving Twostripe Corydoras! These easy-to-care-for Catfish are a favourite among fish enthusiasts and can brighten up any community tank. With their placid and timid nature, Twostripe Corydoras is a great addition to any peaceful non-aggressive, non-predatory fish community. They are also active during the day and early evening, making them perfect for those who love to watch their fish in action. To keep these social creatures happy, you 'll want to keep them in small shoals of at least six individuals, though having a larger group of twelve to twenty-four fish will create an even more vibrant and entertaining display. And don 't forget to give them plenty of hiding spots among the plants, as these Corys love to explore and hang out in the shade. Regarding appearance, Twostripe Corydoras are easy to spot with their flat-bellied body and arched back. They also sport long barbels and a snub snout. Also, look for the two black horizontal lines that run parallel to each other from the gill plates to the caudal peduncle 's top and bottom and the striking gold-flesh-coloured band that runs upwards from the pelvic fins to the base of the dorsal fin. You 'll also notice another black band above the spine that stretches upward and backwards, almost covering the dorsal fin. Some individuals may even have an additional small black patch on their body armour plates. The fins are usually transparent, adding a delicate touch to their overall appearance. All in all, Twostripe Corydoras are a joy to have in your aquarium and are sure to become one of your favourites in no time!

Natural habitat

The Twostripe Corydoras is a captivating species that call the rivers and lakes of South America home. These fish are native to a vast range, from the east of the Andes to the Atlantic coast and from Trinidad to northern Argentina 's Rio de la Plata drainage. You can even spot them in the Rio Cururu of the upper River Tapajós near Maloca Do Conzale in Brazil. Corydoras are fascinating creatures, and the Twostripe variety is no exception. They prefer fast-flowing, clear water and can be found in shaded areas near aquatic vegetation. Stagnant water is a no-go for these active fish, and they thrive in environments that offer plenty of movement and fresh water.

How to breed the Twostripe Corydoras

Corydoras breeding is a unique process compared to other fish. The female Corydoras attaches her mouth to the male 's genital organ to ingest the sperm. The milt is quickly passed through the digestive system and, along with her eggs, is expelled via a pelvic fins pouch. A separate breeding tank with a soft substrate is recommended to breed Corydoras, as these fish enjoy foraging in the substrate for food. The water should be soft, acidic, moderately aerated, and low-light and broad-leaved plants. Slowly replacing up to half of the tank water with collected rainwater daily until spawning can be an effective approach. Conditioning Corydoras with live and frozen foods such as bloodworm, baby brine shrimp, tubifex or mosquito larvae can trigger spawning. As the female nears spawning, she will start cleaning the leaves or aquarium glass surface before laying her adhesive eggs. The female will deposit 2-4 fertilized eggs between her pelvic fins, and the process continues until the female is spent of her eggs. A female can lay up to 100 eggs, taking 2-3 days to complete. Once the eggs have been laid, the parents will not take any further role in raising their offspring and could eat the eggs if given a chance. It is best to return the eggs to the breeding tank. The eggs will hatch within one to three days, and the fry will become free-swimming within two to three days after consuming their yolk sacs. Feeding them on infusoria-type foods is recommended. Once the fry reaches an adequate size, they can be reintroduced to the community tank to join the existing shoal.

Diet & feeding

The Twostripe Corydoras is known for its adaptable feeding habits and is not selective regarding food. A staple diet of high-quality dried food such as flakes, sinking pellets or tablets will suffice, but supplementing their diet with live or frozen fare such as brine shrimp, daphnia, and bloodworm will provide them with the nutrients they need to thrive. To ensure your Corys are in top health and condition, providing them with an ample amount of vegetable matter is recommended. In addition, feeding a diversified diet will not only benefit their health but will also enhance their colouration and vitality.
