Interesting Facts

Agassizii’s corys possess hardened pectoral spines that can pierce human skin, so they should be handled with care. Using a plastic container for transfer is recommended, as their spines may become entangled in a net.

These fish are known for their unique breeding behavior. The female holds 2-4 eggs between her pelvic fins, where the male fertilizes them. She then swims to a suitable spot to attach the sticky eggs. This process is repeated until about 100 eggs are fertilized and attached.

Agassizii’s corys are facultative air-breathers, meaning they can gulp air from the surface when necessary. This adaptation allows them to survive in environments with low oxygen levels.
