Palespotted Corydoras (Corydoras gossei)

The Palespotted 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 are an excellent addition to any community aquarium and display charming behaviours.

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 Plespotted Corydoras 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 other bottom-dwelling species that may become territorial such as Rainbow Sharks, as these Corys can soon become intimidated.

Setting up the aquarium for the Palespotted Cory is relatively simple; however, they require high water quality. Their health can decline fast if you do not regularly perform water changes and clean the aquarium substrate thoroughly.

The substrate should either be sand or smooth gravel, and adding plants and decor such as bogwood or smooth rocks to the aquarium will be beneficial as it will provide cover for your fish. Nevertheless, you must ensure there are no sharp edges on the decor as this may damage or injure the fish.

Adding heater guards in your aquarium may also be helpful, as this prevents your fish from getting burnt on a bare heater, although this rarely happens. Finally, the lighting in your aquarium should be reasonably dim as these Corys do not appreciate bright lighting.

The Palespotted Corydoras have a brownish head, greyish colouration on the upper half of their body and a creamy colouration on their lower half. Their Pectoral pelvic and dorsal fins display a yellow-orange colouration on the top edge, but the rest of their fins are usually transparent. In addition, Their caudal fin is translucent with 3 to 4 rows of transverse dark lines.

In the home aquarium, the Palespotted 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 challenging to differentiate between a male and female Palespotted Corydoras. However, females are typically larger and fuller-bodied when viewed from above, especially when gravid. In contrast, males are slightly smaller and slimmer than females.
