False Armatus Corydoras (Corydoras sp)

The beautiful False Armatus Corydoras, also known as the Sword Corydoras, or CW045, are uncommon in the aquarium hobby.

They are considered one of the more highly desirable cory catfish and have been warmly welcomed by many enthusiasts because of their unique and attractive markings.

Because of their scarcity, they are somewhat expensive and lean towards the higher end of the corydoras price spectrum.

False Armatus Corydoras are peaceful, personable and sociable fish that would make an excellent member of any peaceful community aquarium or a species-only aquarium if you endeavour to breed them.

Because of this fish's lofty price tag and sensitivity to poor water conditions, they would be unsuitable for the beginner aquarist. They are also one of the largest corydoras species, so they would not be recommended for a nano or small setup.

In nature, these Corydoras shoal together; thus, it would be best to keep them in a group of at least six individuals; otherwise, they may become withdrawn, easily stressed, and more susceptible to illness.

False Armatus Corydoras would thrive with other small to medium peaceable tankmates such as Danios, Rasboras and Tetras, as well as Pencilfish, Dwarf cichlids, smaller Barbs and Otocinclus Catfish.

It is also acceptable to house these Corydoras with shrimp and aquarium snails. Nevertheless, it would be best if you did not keep them with considerably larger or aggressive fish.

Ideally, it would be best to house these fish on fine sand as a substrate in your aquarium, although smooth gravel can also be used. These Corys prefer softer water; however, these fish are pretty flexible as long as you avoid sudden changes in water parameters.

Aquarium decor is unnecessary; however, you should endeavour to provide some cover using driftwood, bogwood, rocks or tall or floating aquatic plants, so these fish have some security if needed.

False Armatus Corydoras have a unique tall body shape and somewhat variable colouration depending on their environment. These Corys have dark grey body colouration and a distinct black band across their eye, with a stunning orange patch at the top of their head. In addition, these fish have a longer dorsal fin than most Corydoras, and they have rusty coloured transparent fins.

In the home aquarium, the False Armatus 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 can be challenging to discern between the male and female False Armatus Corydoras. However, the females typically grow larger, and when they are sexually mature, they are noticeably rounder and broader-bodied than the males, especially when distended with eggs.
