Reticulated Corydoras - Corydoras reticulatas : Complete Fish Profile & Care Guide

Table of contents


The Reticulated Corydoras is an excellent choice of Catfish for an established community aquarium. These Corys are good-looking unique fish that are relatively easy to keep and are suitable for the beginner aquarist as these fish are hardy and undemanding. The Reticulated Corydoras is a peaceful shoaling fish best kept in groups of at least six individuals. Keeping these Corys in more significant numbers will result in a much more natural-looking aquarium and makes for an interesting display. You can house Reticulated Corydoras with most fish available in the hobby, including Dwarf Cichlids, Tetras, small to medium-sized Barbs, Gouramis and other peaceful Catfish. These Corys may prey on some more petite Dwarf Shrimp but are safe with larger shrimp and other ornamental invertebrates. However, it would be best if you refrained from keeping these fish with larger, more aggressive fish as they will feel intimidated and get outcompeted for food. In order to protect the delicate barbel area, these corys should be kept on soft sand substrates. In addition, this somewhat shy species will also feel more secure with plenty of bogwood and shady planted areas. As these Catfish are very sensitive to elevated nitrate levels, frequent partial water changes are necessary. In addition, this species does not fare well at high temperatures. Reticulated Corydoras have silver bodies with dark swirly patterns covering their body and a very contrasted flag tail pattern. In addition, these Corys have a large dark blotch over much of their dorsal fin in

Sexual Dimorphism

The difference between the male and female Reticulated Corydoras is usually quite apparent when adequately conditioned. As females have a larger underbelly, they will appear wider from the top. The length of males is also shorter than that of females.

Natural habitat

The Reticulated Corydoras originates from the Amazon River at Monte Alegre in ParĂ¡ State in Brazil, South America. These fish inhabit shallow waters with moderate currents and sandy substrate, where you will find them in large aggregations.

How to breed the Reticulated Corydoras

To breed Reticulated Corydoras, having a separate tank with two or more males per female would be best. When the females are noticeably full of eggs, you should perform a significant 50 to 70 per cent 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. The Reticulated Corydoras will deposit its eggs on the tank glass, amongst fine-leaved plants or within submerged spawning mops. 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 the same water parameters as the spawning tank and be similarly well-oxygenated. Some breeders will add a few drops of methylene blue or place alder cones into the raising tank to stop the eggs from developing fungus. The incubation period is usually 2 to 4 days, and once the fry has consumed their yolk sacs, you can provide them with small live foods like microworm and baby brine shrimp. Corydoras fry can be quite challenging to raise, requiring excellent water quality. Still, they seem less susceptible to diseases when maintained over a thin layer of sand instead of a bare tank.

Diet & feeding

In the home aquarium, the Reticulated 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. Additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide other 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, consuming some vegetable matter. Although most modern fish foods consider this 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.
