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. These Corys may occasionally display a dark band extending down from the top of their heads to the base of their caudal fins. Their belly is whitish.

In the home aquarium, the Horsemans 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 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.
