Twostripe Corydoras (Corydoras bifasciatus) Species Profile & Care Guide

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 of the Twostripe Corydoras

Twostripe Corydoras are endemic to the east of the Andes to the Atlantic coast and from Trinidad to the Rio de la Plata drainage in northern Argentina. You can also find them in Rio Cururu of the upper River Tapajos near Maloca Do Conzale in Brazil in South America. They inhabit rivers and lakes where they enjoy relatively fast-flowing water that is clear and clean as they do not like stagnant water. They also prefer shaded areas by aquatic vegetation.

Diet

The Twostripe Corydoras is an unfussy eater and will eat a wide variety of foods. High-quality dried food such as flakes, sinking pellets or tablets, should be their primary diet but it would be better to supplement their diet with live or frozen fare such as brine shrimp, daphnia and bloodworms.

It is also recommended that you provide your Corys with plenty of vegetable matter as feeding a varied diet will ensure your fish are in optimum health and condition.

Sexing the Twostripe Corydoras

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.

Breeding the Twostripe Corydoras

Corydoras breed somewhat differently from other types of fish. The female will connect her mouth to the genital organ of the male and drink the sperm. The milt then moves swiftly through the digestive system and will then be expelled, together with her eggs through a pelvic fins pouch.

If you plan to attempt to breed Corydoras, then it is recommended that you have a breeding tank prepared. Such a tank can be empty, but a soft substrate is advised, as your Corydoras will prefer to feed by foraging in the substrate for food.

The water needs to be somewhat soft and acidic and have moderate aeration as Corydoras do not enjoy still water. The tank should also have a low level of light and contain broad-leaved plants. Manage your tank heating so that you can slowly remove up to half of the tank water and then replace it with collected rainwater and repeat this daily until the Corydoras spawn.

Conditioning your Corydoras on live and frozen food such as bloodworm, baby brine shrimp, tubifex or mosquito larvae will also help to trigger spawning.

As the female comes close to spawning, she will start cleaning the surface of leaves or the aquarium glass on which she will lay her adhesive eggs.

The female will hold 2 to 4 fertilised eggs between her pelvic fins and then deposit them in one of the areas that she has been previously preparing. The process will continue until the female is spent of her eggs. Generally, a female will lay up to 100 eggs, taking two to three days to complete.

When the eggs have been laid, the parents will take no further role in raising their offspring and could consume the eggs if given a chance, so it's best to return them to the breeding tank.

It takes one to three days for the eggs to hatch, depending on the temperature and water conditions, then two to three days for the fry to consume their yolk sacs and become free-swimming. Once free-swimming, you can then feed them on infusoria type foods.

Once the fry is sufficient in size and not seen as a snack, you may then introduce them back into the community tank where they can join the existing shoal.
