Interesting Facts

The Pinkthroat corydoras is known for its unique behavior of occasionally darting to the water surface to gulp air, a normal activity that aids in respiration. Additionally, they are egg depositors, often placing adhesive eggs among plants or on aquarium glass. Spawning can be induced by simulating natural conditions, such as performing partial water changes with slightly cooler water before a rainstorm.

Why do Pinkthroat corydoras gulp air at the surface?

This behavior allows them to supplement their oxygen intake, especially in environments with lower oxygen levels.
