Blacktop Corydoras is a small tropical freshwater fish with the scientific name Corydoras acutus.
It belongs to the subfamily Corydoradinae, which is part of the family Callichthyidae.
This fish comes from South America and is found in the Amazon River basin in Ecuador and Northern Peru.
It was first described by Edward Drinker Cope in 1872.
It lives in tropical waters with a pH between 6.0 and 8.0, water hardness between 2 and 25 dGH and temperatures between 77°F and 83°F (25°C to 28°C).
It eats worms, small crustaceans, insects, and plant matter.
When reproducing, the female blacktop cory lays her eggs in dense vegetation, and the adults don’t guard them.
The female holds 2 to 4 eggs between her pelvic fins while the male fertilizes them for about 30 seconds.
Then, the female swims to a suitable spot and attaches the sticky eggs.
They repeat this process until around 100 eggs have been fertilized and attached.
Blacktop Corydoras is popular in the aquarium trade industry, which means people like to buy them for their home aquariums.
