Black Diamond Corydoras CW49 - Corydoras sp : Complete Fish Profile & Care Guide
Table of contents
Introduction
Black Diamond Corydoras (Corydoras sp). is an excellent-looking, friendly, peaceful bottom dweller perfect for a community aquarium with other non-aggressive fish with comparable water requirements. These Corys will generally keep to themselves and spend much of their time scavenging around the tank's bottom. The Black Diamond Corydoras are shoaling species in nature, so it is recommended that you keep them in groups of at least six individuals, preferably more. The more Corys you have, the more secure they will feel, and the more they will display better behaviours. Ideal tankmates for the Black Diamond Corydoras could include small to medium Tetras, Danios, Rasboras, Hatchetfish and Livebearers, Gouramis, Dwarf Cichlids, Loaches and other peaceful Catfish. However, it would be best if you did not house them with anything large or aggressive. If you intend to breed these Corys, you should keep them in a species only aquarium to avoid other greedy fish consuming any of their eggs. These Corys will thrive in an aquarium with a soft sandy substrate and plenty of shelters using driftwood or bogwood. These fish will also appreciate some areas of dense planting, as this will give your fish security. Like most Corydoras, these fish are sensitive to deteriorating water conditions; therefore, a good maintenance schedule is essential. Make sure you keep the substrate clean and perform regular significant water changes. The Black Diamond Corydoras have a tan-coloured body, and they possess a black mask over their eyes. In addition, these fish display a large black diamond-shaped blotch that runs from their stomach into their dorsal fin and ends at the top of the first dorsal fin ray. All the other fins of these Corys are transparent.Black Diamond Corydoras CW49 Photos
Sexual Dimorphism
It can be challenging to differentiate between the male and female Black Diamond Cory. However, females grow a little larger than males, and sexually mature individuals will have rounder bodies. In contrast, males are slimmer and slightly smaller than females.Quick Facts

Natural habitat
The Black Diamond Corydoras is very rare and haven't been officially described as of yet, so, unfortunately, there is very little information on their habitats. However, we know these Corys are found in a small creek with soft, acidic shallow water and sandy substrate, which enters the Putumayo River in Colombia in South America. However, these Corys are likely to be far more widespread.How to breed the Black Diamond Corydoras CW49
There is currently no information on the breeding habits of the Black Diamond Corydoras in the home aquarium; however, they will probably breed in a similar fashion to other Corydoras species. It would be best to set up a separate breeding tank and place two or more males than females in it. Then, 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 flow and oxygenation in the tank. You should repeat this daily until the fish spawn. The Black Diamond Cory 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 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.Diet & feeding
Black Diamond Corydoras are unfussy eaters and will eat a wide variety of foods. High-quality sinking dried foods such as pellets or wafers should be their primary diet; however, you should supplement their diet with either live, frozen or freeze-dried foods such as brine shrimp, daphnia, and bloodworm. These Corys will also appreciate the occasional vegetable treat.Other Corydoras you maybe interested in
