Breeding Process

The breeding process of Copeina guttata, also known as the Red-Spotted Copeina Tetra, involves fascinating behaviors and intricate reproductive strategies.

During breeding, the male fish prepares a pit in the sand where the eggs will be laid. The male then prods and drives the female towards the pit and opens a pocket below her genital opening. The female releases her eggs into this pocket for fertilization.

Once the eggs are fertilized, the male takes on the responsibility of guarding them. He fans the eggs with his fins to provide proper oxygenation and protects them from predators.

The eggs typically hatch within 24 to 40 hours at a temperature of 75°F. Even after hatching, the male continues to guard the fry, ensuring their safety and well-being.

The active participation of the male in breeding behavior and parental care makes the Red-Spotted Copeina Tetra an intriguing species to observe and adds interest to any aquarium.
