Araguaia Corydoras - Corydoras araguaiaensis : Complete Fish Profile & Care Guide

Table of contents


Araguaia Corydoras is a small, attractive and social species that prefers to swim in groups of at least six individuals. The species exhibits schooling behaviour and can be found in the lower to the middle water column. These Corys are peaceful and non-aggressive and can be kept with other small, peaceful species in the aquarium. Ideal tankmates for Araguaia Corydoras could include small to medium Characins and Cyprinids as well as Dwarf Gouramis, Dwarf Cichlids and other peaceful Catfish. However, it would be best if you didn't house them with anything aggressive or huge. The ideal aquarium environment for these Corys would be well-planted with some driftwood to hide in and a sandy substrate. These fish will also need a sound filtration system and a moderate water flow. These Corys are small and chubby fish, reaching a maximum length of 6 centimetres. Their bodies are rounded and slightly flattened, with a pointed snout and short barbels protruding from their mouth. These fish have a silvery beige base colour with varying-sized black spots covering the body and fins. All their fins are transparent.

Sexual Dimorphism

It is simple to differentiate between the male and female Araguaia Corydoras. From above, the female's body is widest in the centre, while the males is widest behind its pectoral fins. The females also have a rounded pectoral fin. In addition, the female is always plumper when well-fed or in breeding conditions. In contrast, males usually are smaller and have longer pectoral fins than females, and their pelvic fins are more pointed.

Natural habitat

Araguaia Corydoras can be found in the Araguaia River Basin in Brazil in South America. These Corys inhabit clear and shallow water environments such as small tributaries, flooded fields, and flooded forests. These habitats are characterised by sandy or muddy substrates and dense vegetation cover, and their range is limited to this area and is not known to occur outside of their native range.

How to breed the Araguaia Corydoras

Like other members of the Corydoras genus, Araguaia Corydoras is an egg layer and can breed in captivity. The fish is a relatively easy species to breed, typically spawning on a flat surface. The females will lay clutches of eggs, and the male will fertilise them. The eggs will hatch in about four days, and the fry will become free-swimming in another four days. After that, you can feed the fry newly hatched brine shrimp, crushed flake food, and other small, high-quality foods.

Diet & feeding

In the home aquarium, Araguaia Corydoras will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements. Additional foodstuffs such as live, frozen, and freeze-dried meals such as mini bloodworm, daphnia, and tubifex once or twice a week will provide other benefits to your fish's health and well-being but is not a must for this fish. This fish is an omnivore in the wild, consuming some vegetable matter. Although most modern fish foods consider this and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.
