Threestripe Corydoras Physical Characteristics

Size: 2.4 inches (6.1 centimeters)

Threestripe corydoras can grow up to 6.1 centimeters (2.4 inches) in length.

This is popular in the aquarium trade industry but is often mistakenly sold as Julii corydoras.

The main difference between the two species is their markings.

Threestripe corydoras has a reticulated pattern, while Julii corydoras has leopard spots.

The best way to tell them apart is by looking at the stripes on their sides.

Threestripe corydoras has more pronounced and solid stripes.

Threestripe Corydoras Reproduction

During the breeding process, the female threestripe corydoras holds 2 to 4 eggs between her lower fins.

The male then fertilizes these eggs for around 30 seconds.

After that, the female swims to a safe location and sticks the eggs onto a surface.

They continue this process until they have fertilized and attached about 100 eggs.

They usually spawn, or lay eggs, in groups with other threestripe corydoras.
