What should their diet consist of?

As omnivores, they thrive on a varied diet of high-quality sinking pellets, supplemented with live or frozen foods such as bloodworms, brine shrimp, and daphnia.

Are there any specific challenges in caring for Adolfo’s cory?

They are sensitive to poor water quality and abrupt changes in parameters. Regular water changes and monitoring are essential to prevent stress and disease.

Origin and Habitat

Adolfo’s cory is indigenous to the upper Rio Negro basin in Brazil. In the wild, they inhabit slow-moving, blackwater rivers and streams characterized by soft, acidic water and dense vegetation. The substrate in these environments is typically composed of fine sand and leaf litter, providing ample hiding spots and foraging grounds.

What type of environment does Adolfo’s cory naturally inhabit?

They are found in slow-moving, blackwater rivers with soft, acidic water and dense vegetation.

Interesting Facts

Adolfo’s cory is named after Adolfo Schwartz, a renowned Brazilian ichthyologist who contributed significantly to the study of South American fish species. One of their unique behaviors is the occasional gulping of air at the water's surface, a trait that allows them to absorb oxygen through their intestines—a fascinating adaptation to low-oxygen environments.

Why do Adolfo’s cory occasionally gulp air at the surface?

This behavior enables them to absorb atmospheric oxygen through their intestines, an adaptation to survive in low-oxygen waters.

What is unique about their breeding behavior?

They exhibit a "T-position" during spawning, where the male fertilizes eggs held by the female before she attaches them to surfaces like plant leaves or aquarium glass.
