Concolour Corydoras - Corydoras concolor : Complete Fish Profile & Care Guide
Table of contents
Introduction
A Concolor Corydoras makes a fantastic community aquarium fish due to its small size, peaceful nature, and hardiness. However, to create a beautiful display and let these sociable, shoaling fish feel more comfortable, they should be kept in groups of at least six, preferably more. Since Slate Corydoras are prone to barbel infections, keeping them on sand rather than gravel, where waste can build up unseen, is essential. To keep Concolor Corydoras healthy, regular maintenance should be carried out, including frequent partial water changes. Plant densely and provide shady retreats amongst bogwood. You can keep Concolor 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. The Concolor Corydoras have a greyish-brown body colour with hints of greens or blues when in good condition. In addition, all their fins have an ochre-to-orange colouration with no markings, and they have a black band that runs through their eyes.Concolour Corydoras Photos
Sexual Dimorphism
It is somewhat straightforward to differentiate between the male and female Concolor Corydoras. Adult males will develop an extended dorsal fin and will be a little shorter than females. In contrast, the females grow larger and are noticeably rounder and broader than males, especially when carrying eggs.Quick Facts

Natural habitat
Concolor Corydoras are endemic to the softwater streams of Las Mangas, a tributary of the Río Parguaza, the western part of the State of Bolivar in Venezuela, South America.How to breed the Concolour Corydoras
To breed Concolor 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. These Corys will deposit their 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
The Concolor 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.Other Corydoras you maybe interested in
