Vulcan Corydoras (Corydoras sp)

Vulcan Corys are a relatively new species that carries a high price tag; however, they are a stunning Catfish. These Corys are peaceful and sociable fish that would make an excellent member of a community aquarium with other harmonious species or a species-only aquarium. However, this fish's sensitivity to water conditions makes them unsuitable for the beginner aquarist.

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together; therefore, it would be best to keep them in a group of at least six individuals; otherwise, they may become withdrawn, easily stressed, and more susceptible to illness.

Vulcan Corys would be best housed with other small to medium peaceable tankmates such as Rasboras, Danios and Tetras, as well as Pencilfish and Dwarf Cichlids, smaller Barbs and Otocinclus Catfish. It is also acceptable to house these fish with shrimp and aquarium snails. However, you should not house them with aggressive fish, as they may get harmed by Cory's venomous spines if they try to attack them.

Ideally, it would be best to use fine sand as a substrate in your aquarium, although smooth gravel can also be used, as long as you clean it regularly. Aquarium decor is not necessary; however, you should provide some cover using driftwood, bogwood, rocks or tall or floating aquatic plants, so these fish have some security if needed. It would also benefit your fish if you added some dried leaf litter.

The Vulcan Cory has a silvery-beige body contrasted with dark irregular patterning consisting of numerous lines and spots that spread through to all of their fins. In addition, this Catfish has a very long and prominent dorsal fin and a short snout.

In the home aquarium, the Vulcan 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 simple to differentiate between male and female Vulcan Corys. Females are usually slightly larger and fuller-bodied when viewed from above, especially when gravid and have a much smaller and rounder dorsal fin than the males. In contrast, males are slightly smaller and slimmer than females and have an elongated and pointed dorsal fin.
