Eversi Corydoras (Corydoras Eversi)

The Eversi Corydoras is very uncommon in the aquarium hobby. However, these Corys are lively, distinctively patterned fish perfect for the nano, community, and planted aquarium.

The Eversi Corydoras is a peaceful shoaling fish that is best kept in groups of at least six individuals. Keeping these Corys in more significant numbers will result in a much more natural-looking aquarium and makes for an interesting display.

You can house Eversi Corydoras with most fish available in the hobby, including Dwarf Cichlids, Tetras, small to medium-sized Barbs, Gouramis and other peaceful Catfish. These Corys may prey on some smaller Dwarf Shrimp but are safe with larger shrimp and other ornamental invertebrates. However, you should avoid keeping these fish with larger, more aggressive fish as they will feel intimidated and get outcompeted for food.

Eversi Corys will thrive in an aquarium set up to imitate an Amazon biotope. You will need a sandy or smooth gravelled substrate, a few driftwood branches, and some dried leaf litter to achieve this. You will not find aquatic plants in these Cory's natural habitats; instead, allow the wood and leaves to stain the water a brown colour, remove old leaves and replace them every few weeks so they don't decay and degrade the water. If a biotope setup is not your cup of tea, these Corys will also do well in a typical well-planted aquarium.

Eversi Corys are sensitive to deteriorating water conditions, so it is essential that you have a good maintenance regime and avoid any sudden changes. It would be best to perform frequent water changes and not overfeed your Corys; other than that, these fish are undemanding and relatively easy to look after.

The Eversi Corydoras has a rounded head and snout. Similar to many other species, its colour pattern is light with dark dots on its head, forming horizontal lines down the body and dorsal fin. These Corys also have faint vertical lines around the tail. The fish has a distinctive yellowish-orange base colour, contrasting with its white belly. Depending on the fish's diet, lighting, and surroundings, this colour can be brighter or paler.

Feeding

In the home aquarium, the Eversi 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 pretty challenging to differentiate between a male and a female Eversi Corydoras. However, females usually grow a tad larger than males, and sexually mature individuals will be rounder and higher-bodied. In contrast, males are slimmer and slightly smaller than females.
