Horsemans Corydoras (Eques Corydoras)

The Horseman's Corydoras is a small, peaceful freshwater Catfish that has become quite popular in the home aquarium. This fish species is easy to care for and incredibly hardy but can be somewhat shy. These Corys make a wonderful addition to any community aquarium; they are incredibly eye-catching because of their bold body marking, and they display fascinating behaviours.

Horseman's Corys are shoaling species in nature; therefore, it would be best to maintain them in a group of at least six individuals, preferably more. Keeping these fish in bigger numbers will allow your fish to feel more comfortable, leading to a much more natural-looking display.

Ideal tankmates for the Horseman's Cory could include smaller species such as Rasboras, small Barbs, Pencilfish, Dwarf Cichlids, Angelfish and Tetras. However, it is recommended that you do not house these Corys with larger, more boisterous or aggressive species as they may be intimidated and outcompeted for food.

The ideal aquarium setup for the Horseman Cory would mimic their natural habitat. To achieve this setup, you should use a substrate of river sand or small-sized smooth gravel, add plenty of driftwood or tree roots and have some low-light ground cover plants like Anubias and Java Ferns or taller plants with larger leaves like Amazon Sword. The plants will help dim the aquarium from the bright light and complete the look.

Adding dried leaf litter to the aquarium is also beneficial as it will provide cover, filter out the light and stain the water brown from tannins which completes the natural feel.

The Horseman's Cory will also do well in a well-planted aquarium and peaceful community aquariums. However, it is essential to have pristine water as this species is sensitive to deteriorating water conditions and high nitrates. Therefore, make sure you have some water flow and do not use under gravel filtration.

The colour of the Horseman's Corydoras can vary depending on what substrate you keep them on. Typically these Corys have a large dark greenish-brown saddle-shaped body marking located on either side of their body and a whitish belly; however, on some, this saddle shape marking may appear a lighter bluish-turquoise colour.

These Corys also have an orange vertical band just behind their eye across their gill plate. You can also find this orange colouration on top of their back and at the edges of their caudal fin. Occasionally, they may exhibit a dark band that begins at the top of their head and continues down to the base of their caudal fin. Their belly is whitish.

Natural Habitat

The Horseman's Corydoras originates from the Amazon River at Codajás, Amazonas in Brazil', which is located midway between Manaus and Tefé on the Rio Solimões main channel in western Brazil in South America. These Corys inhabit small streams and tributaries consisting of a soft sandy substrate, submerged wood, areas of dense vegetation, and open swimming areas.

Feeding

The Horseman's Cory is easy to feed in an aquarium environment. However, make sure you provide them with a varied diet to ensure the fish stay in tip-top condition.

These Corys will readily accept good-quality dried foods such as sinking catfish pellets, wafers and granules, as well as frozen, live and freeze-dried foods such as white mosquito larvae, bloodworm, white worms, grindal worms, vitamin-enriched brine shrimp, Daphnia, and tubifex.

These Corys will also appreciate the occasional green vegetable treat.

Sexual Dimorphism

It can be somewhat challenging to differentiate between the male and female Horseman's Corydoras, especially when they are juveniles. However, females are usually slightly bigger, rounder and broader-bodied than males when full of eggs. In contrast, the males are somewhat smaller and slimmer than the females.

Breeding

The Horseman's Corydoras is relatively easy to breed if you have the correct water parameters. It would be best to place two males with every female into a separate breeding tank with established, well-oxygenated water, ensuring plenty of plants or areas for the female to stick her eggs.

When the females are noticeably full of eggs, you should perform a significant water change with cooler water and increase the oxygenation and flow in the tank. It would help if you then repeated this daily until the fish spawn. Once they are ready to spawn, the pair will perform the classic 'T position; the males will fertilise the eggs between the female's pelvic fins. The female will then deposit the eggs onto decor, plants, or on the sides of the aquarium.

Once spawning is complete, you should remove either the adults or the eggs. If you decide to move the eggs, the raising tank will need to have the same water parameters as the spawning tank and will need to be well-oxygenated.

Some breeders add a few drops of methylene blue into the raising tank, and others use Alder Cones. This helps stop the eggs from developing fungus. The incubation period usually takes between 3 and 5 days, and once hatched, you can provide them with powered fry food for a few days moving on to small live foods such as microworm and baby brine shrimp as they grow.
