Imitator Corydoras (Corydoras Imitator)

Imitator Corys are peaceful and sociable fish that make excellent members of a community aquarium with other temperate species. Ideally, it would be best to keep these fish in a group of at least six individuals; otherwise, they will become withdrawn, easily stressed and more susceptible to illness.

Ideal tankmates for Imitator Corys could include Tetras, Pencilfish, Dwarf Cichlids such as Apistogrammas and smaller Barbs. However, you should not house them with aggressive fish, as they may get harmed by this fish'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 is a satisfactory alternative, provided you clean it regularly. Aquarium decor is not essential; however, you should provide some cover using driftwood branches and aquatic plants, so these fish have some security if needed. It would also benefit your fish if you added some dried leaf litter.

Imitator Corys have a silvery-white body colouration, with a dark diagonal band running across their body's dorsal surface, including the dorsal fin. All the other fins are transparent. In addition, these fish have a dark marking on their head through the eye.

Natural Habitat

Rio Negro


In the home aquarium, the Imitator 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 somewhat straightforward to differentiate between male and female Imitator Corys. Sexually mature females are usually larger, broader, and deeper-bodied than males and have rounded fins. In contrast, males are smaller, slimmer and have pointed dorsal and pelvic fins.
