False Network Corydoras - Corydoras sodalis : Complete Fish Profile & Care Guide

Table of contents


The False Network Corydoras is a unique and attractive freshwater fish species ideal for aquarium hobbyists of all levels. Its peaceful nature and hardy disposition make it a great addition to any community aquarium. To create a beautiful display and give these shoaling fish more confidence to venture outdoors, False Network Corydoras should be kept in groups of 5 or more. It would be best to keep False Network Corydoras with small, peaceable tankmates, such as some smaller-sized Tetras, Peaceful Barbs, Dwarf Gouramis and Dwarf Cichlids. You can also house these Corys with other Catfish and Plecos. False Network Corydoras will thrive in an aquarium set up to imitate an Amazon biotope. You will need a sandy or smooth gravelled substrate, a few driftwood branches, and some dried leaf litter to achieve this. You will not find many aquatic plants in these Cory's natural habitats; instead, allow the wood and leaves to stain the water brown. If a biotope setup is not your cup of tea, these Corys will also do well in a well-planted aquarium with plenty of hiding places made from caves, rocks, and driftwood. False network Corydoras have silvery bodies with black swirly patterns throughout their body and dorsal fin and have black stripes on their caudal fin. These Corys are often confused with the Reticulated Corydoras; however, these Corys lack the black blotch that covers most of the dorsal fin on the Reticulated Corydoras, and in general, their patterning and body colour is not as boldly coloured.

Sexual Dimorphism

It can be somewhat challenging to differentiate between a male and female False Network Corydoras. However, females are usually a little larger than males when fully mature and have wider bodies, especially when they are carrying eggs.

Natural habitat

The False Network Corydoras is endemic to the Amazon River in north-western Brazil and the Rio Yavari in Loreto, Peru, South America. These Corys inhabit shallow waters in streams, tributaries, pools and flooded forests.

How to breed the False Network Corydoras

False Network Corydoras are relatively simple to breed and produce similarly to other Corydoras species. It would be best to set up a separate breeding tank with either a bare bottom or a sand or fine gravel substrate. You should also add an air-powered sponge filter and some clumps of java moss. The ideal temperature for breeding would be around 75 degrees Fahrenheit, and the pH should be approximately 6.5. Using RO water and filtering the water through peat is also helpful. It would also help if you had a higher ratio of males to females when breeding Corys, and two males for every female is ideal. It would be better to condition the group on a mixed diet of dried, live and frozen foods, as this will help to encourage spawning. Once you can see the females are full of eggs, you should perform a significant water change with cooler water and increase the flow and oxygenation in the tank, then repeat this daily until the fish spawn. When the fish are ready to spawn, you may notice increased activity; the males will pursue the females. When the females are prepared, they will allow the male to touch her with their barbels, where they will then take up the classic T-position. The female will then form a basket with her pelvic fins where she will place 1 to 4 eggs. Once the eggs are fertilised, she will swim away and find a suitable place to deposit the eggs, usually on the tank's glass near the water with a fast current. This cycle is then repeated until she has no more eggs. Once spawning is complete, you should remove either the adults or the eggs; otherwise, they will be consumed. If you decide to move the eggs, you will find they are pretty strong and can be easily rolled up the glass with a finger. The new tank should be oxygenated and have the same water parameters as the breeding tank. Adding a few drops of methylene blue to the water would be better to prevent the eggs from getting fungus; however, some eggs may still have fungus, so you must remove them immediately to prevent it from spreading. The eggs will usually hatch between 3 and 5 days later, and the fry will initially feed on their yolk sacs. Once they have finished their yolk sacs, you must provide them with microworms and baby brine shrimp. The babies appear less susceptible to disease if you keep them in a tank with a thin layer of sand rather than a bare bottom.

Diet & feeding

In the home aquarium, False Network 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 mini 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. 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.
