Incubation is normally 3-4 days and once the fry have fully-absorbed their yolk sacs they are able to accept small live foods such as microworm, Artemia nauplii, etc. Most breeders add a few drops of methylene blue, or an alder cone or two at this point in order to prevent the eggs developing fungus. The new container should contain the same water as the spawning tank and be similarly well-oxygenated. Once spawning is complete either adults or eggs should be removed the latter can usually be rolled gently up the glass with a finger. Repeat this daily until the fish spawn.Įggs may be deposited on the aquarium glass, among fine-leaved vegetation or within sunken spawning mops, with the latter particularly recommended since they facilitate easy removal of eggs. Use a ratio of two or more males per female if possible, and when the females are visibly full of eggs perform a large (50-70%) water change with cooler water, and increase oxygenation and flow in the tank. ReproductionĬan be bred in a similar fashion to many other Corydoras species.

In the rio Negro basin such habitats typically contain tea-coloured water with very little detectable hardness, low conductivity, and a pH of 4.0-6.0, with other fishes comprising small characids, lebiasinids, and dwarf cichlids of the genus Apistogramma. Inhabits pristine blackwater tributaries and areas of flooded forest where the water is characteristically stained dark with organic chemicals. Type locality is ‘Upper Rio Negro, eastern Amazonas, Brazil’, which is thought to refer to forest brooks crossing the “new army road” north of São Gabriel da Cachoeira municipality, thus corresponding to the Igarapé Muiá (00☀9’03″N 66☄8’10″W).
