Twostripe Corydoras (Corydoras bifasciatus)

The Twostripe Corydoras is a Placid and timid shoaling fish, but it is also great fun to sit and watch. These Corys are easy to care for and hugely popular.

This Corydoras makes an excellent community fish as long as the community is one of non-aggressive, non-predatory species. Twostripe Corydoras is suitable for all community aquariums.

Twostripe Corydoras prefer to live in small shoals, so it is recommended that you purchase at least six individuals, but twelve to twenty-four fish would be more beneficial. Unlike other Catfish, they are active during the day and early evening rather than during the night. Corydoras enjoys being in the shade, so having a well-planted tank is advisable.

The Twostripe Corydoras has a flat-bellied body and an arched back ahead of the dorsal fin. These fish are also characterised by having a reasonably snub snout and relatively long barbels.

The Twostripe Corydoras has two black, horizontal lines running parallel to each other from behind the gill plates to the caudal peduncle's top and bottom. They have a grey head, darkening towards the gill plates, then a striking gold-flesh-coloured band running upwards from the pelvic fins, along the front of the gill plates and up to the base of the dorsal fin.

A further black band starts above the spine, from behind the gill plates and stretches upward and backwards, almost covering the dorsal fin. The fins are generally transparent. You may find that some individuals may also display an additional small black patch on body armour plates.

Natural Habitat

Rio de la Plata


In the home aquarium, the Twostripe 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.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account 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.

Sexual Dimorphism

It is relatively easy to distinguish the sex of the Twostripe Corydoras. Males tend to be somewhat slimmer, more distinct, and their colouring is more intense in the body than the female. In contrast, the female is usually more extensive and more profound, especially when full of eggs and are duller than males.
