Emerald Brochis Corydoras (Corydoras splendens)

The Emerald Brochis Corydoras is a prevalent species due to its peaceful disposition and metallic green colouration. This Cory is an energetic, distinctively marked fish perfect for a community or a well-planted aquarium.

It would be best if you kept Emerald Brochis Corys in groups of at least six individuals as they will be much more active and confident with their kind as they are shoaling species in nature. Ideal tankmates for these Corys could include small to medium Tetras, Danios, Rasboras and Livebearers, as well as Gouramis, Dwarf Cichlids, Loaches and other peaceful Catfish. However, it would be best if you didn't house them with anything aggressive or huge.

If you intend to breed these Corys, you should keep them in a species only aquarium to avoid other greedy fish consuming any of their eggs.

The Emerald Brochis Corydoras will thrive in an aquarium that mimics their natural environment. To achieve this, you could use a sandy substrate and add some driftwood; standard beech is also ok to use if you thoroughly dry it and strip it of its bark. Having dim lighting will also benefit your fish.

Adding some dried leaves to stain the water would complete the natural feel; however, make sure you replace them every few weeks so they do not rot and pollute the water. Adding some aquarium-safe peat to the filter can aid in simulating black water conditions. Although you will not find aquatic plants in this Cory's natural waters, they also enjoy a well-planted aquarium.

The Emerald Brochis Corydoras is sensitive to deteriorating water conditions; therefore, a good maintenance schedule is essential. Like all Corys, this species may lose their barbels if you keep them in poor water, so make sure you keep the substrate clean and perform regular significant water changes.

The Emerald Brochis Corydoras has a body that reflects a metallic green, bluish-green, or even a bluish colour depending upon the lighting angle. The ventral area is yellowish, as are the ventral, pectoral and anal fins, and the caudal, adipose and dorsal fins are translucent brownish.

In the home aquarium, the Emerald Brochis 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 is relatively straightforward to differentiate between the male and female Emerald Brochis Corydoras. The females are usually larger and fuller bodied than the males and have a pinkish belly. In contrast, males are slimmer, smaller and have yellow bellies.
