Spotted Corydoras CW27 - CW027 : Complete Fish Profile & Care Guide
Table of contents
Introduction
The attractively patterned CW27 Spotted Corydoras are fairly uncommon in the hobby. However, these corys are peaceful, hardy and undemanding, making them perfect candidates for a community aquarium and suitable for both beginner and advanced aquarists. You will find Spotted Corydoras hanging out in large groups in the wild; therefore, you should keep these corys in a group of at least six individuals, preferably more. Keeping these Corys in larger numbers will deliver a stunning display and make your fish feel more comfortable, bringing them out more frequently. Ideal tankmates for the Spotted Corydoras could include small, peaceable tankmates such as small to medium-sized Cyprinids, Characins, Dwarf Gouramis and Dwarf Cichlids. However, it would be best to avoid housing these fish with much larger, more aggressive species as they will feel intimidated and may refuse to eat. It would be best if you used a soft sandy substrate in the aquarium and provided your Corys with some shelter using driftwood or bogwood alongside some areas of dense planting, as this will give your fish security. You should regularly maintain your aquarium; this includes cleaning the substrate and frequent partial water changes. The Spotted Corydoras has a creamy-coloured body contrasted with dark spots that begin behind the gill plates and continue to the base of the caudal fin. These spots fade as they get near the belly of the fish. These Corys also have a dark band that runs vertically over its head and ends below each eye. A further grey band starts behind the gill plates and extends up the dorsal fin's frontal half. The remaining fins are generally transparent except for the caudal fin, which possesses six to eight narrow dotted vertical stripes that start on the caudal fin base and fade as they move to the edge of the caudal fin.Spotted Corydoras CW27 Photos
Sexual Dimorphism
It can be fairly challenging to differentiate between a male and female Spotted Cory. However, females usually grow a tad larger than males, and sexually mature individuals will be rounder and higher-bodied. In contrast, males are slimmer and slightly smaller than females, have bolder patterning, and have a higher dorsal fin. Quick Facts

Natural habitat
The Spotted Corydoras originates from the Río Orinoco River Basin in Venezuela and can be found in coastal drainages in Suriname in South America. These Corys inhabit clear, slow-moving shallow rivers and streams with dense vegetation. These fish prefer a softer substrate and are typically seen in sandy or muddy-bottomed areas with plenty of mulm or leaf litter.

How to breed the Spotted Corydoras CW27
There is currently very little to no information on how to breed the Spotted Corydoras, and there are no records on the successful breeding of these Corys in the home aquarium; however, they will more than likely breed similarly to other Corydoras species. It would be best to have a separate tank with two or more males per female. 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 Spotted 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 3 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 Spotted Corydoras is a scavenging omnivore that will accept most sinking dried foods such as algae wafers or pellets, alongside small live and frozen food such as mosquito larvae, Tubifex and bloodworm. It would also benefit your Corys if you provided them with plenty of vegetable matter, as feeding a varied diet will ensure your Corys are in optimum condition and healthy.Videos
