Venezuelan Orange Corydoras (Corydoras venezuelanus)
The Orange Venezuelan Corydoras is a very peaceful and active fish that will adapt to most freshwater conditions as long as you regularly maintain the aquarium and avoid sudden changes in water parameters. These fish are definitive scavengers that will inhabit and feed on the bottom of the aquarium. These Corys are ideal for an established subtropical community aquarium and would be best maintained in groups of 6 or more individuals due to their shoaling nature.
Ideal tankmates for the Orange Venezuelan Corydoras would be peaceful fish that enjoy similar water conditions. These could include Dwarf Cichlids like Electric Blue Rams, Cardinal Tetras, Angelfish, Common Otocinclus, Rasboras, White Cloud Mountain Minnows and Danios. These Corys may prey on some smaller dwarf shrimp, but larger shrimps such as the Amano Shrimp and most other peaceful ornamental invertebrates should be fine. However, if you intend to breed these Corys, you should keep them in a species-only aquarium.
Orange Venezuelan Corydoras will thrive in an aquarium with a sand substrate, or very smooth gravel as coarse substrate can damage its delicate barbels and underbelly. It would benefit your Corys if you provided them with plenty of shady areas using driftwood, rocks, and areas of thick planting. Additionally, these fish will need areas with moderate water movement and proper oxygenation. Lastly, filtration should be efficient, and standard maintenance, including regular partial water changes, must be performed to keep these fish in excellent condition.
The Orange Venezuelan Corydras has a large, greenish-blue black oval spot covering the shoulder, a bright orange colour along its back as it matures and a distinguishable, iridescent brownish-red spot on the back of the neck.

The Orange Venezuelan Corydoras is endemic to the Rio Tuy and Lake Valencia drainages of northern Venezuela in Aragua, Miranda, and Carabobo. You can also find these Corys in nearby Orinoco drainage streams and rivers such as the Rio Chirgua in South America. These fish inhabit streams and rivers' lower reaches of clear, cooler waters. These Corys have a unique capability to breathe air from the water's surface, making them one of the few fish that can thrive in stagnant water.
Orange Venezuelan Corydoras are foraging omnivores that will accept almost anything you give them; however, you should offer them a varied diet to help keep them healthy.
It would be best to provide your Corys with good quality dried sinking foods such as algae wafers and pellets as the staple diet supplementing that with small live frozen or freeze-dried foods like daphnia, mosquito larvae, Tubifex, brine shrimp and bloodworm.
Under no circumstances should your Corys be expected to survive on leftover food from other tank inhabitants of the aquarium or relied upon to clean the aquarium.
It can be somewhat challenging to distinguish the males from female Orange Venezuelan Corydoras, especially when they are juveniles. However, females are usually slightly bigger, rounder and broader-bodied than males when full of eggs. In contrast, the males are somewhat smaller and slimmer than the females.
The Orange Venezuelan Corydras are relatively easy to breed as long as you have the correct water parameters. It would be best to place two males with every female into a separate breeding tank with established, well-oxygenated water, making sure there is plenty of plants or areas for the female to stick her eggs.
When the females are noticeably full of eggs, you should perform a significant water change with cooler water and increase the oxygenation and flow in the tank. It would help if you then repeated this daily until the fish spawn. Once they are ready to spawn, the pair will perform the classic 'T position; the males will fertilise the eggs between the female's pelvic fins. The female will then deposit the eggs onto decor, plants, or on the sides of the aquarium.
Once spawning is complete, you should remove either the adults or the eggs. If you decide to move the eggs, the raising tank will need to have the same water parameters as the spawning tank and will need to be well-oxygenated.
Some breeders add a few drops of methylene blue into the raising tank, and others use Alder Cones. This helps stop the eggs from developing fungus. The incubation period usually takes between 3 and 5 days, and once hatched, you can provide them with powered fry food for a few days moving on to small live foods such as microworm and baby brine shrimp as they grow.
