YELLOW FIN CORYDORAS (Gastrodermus sp. C123)

Yellowfin Corydoras

(Corydoras sp. “Yellow Fin”)

Description

The Yellowfin Corydoras is a peaceful and eye-catching bottom-dwelling catfish known for its soft metallic body tones accented by yellow to golden fins. Like other Corydoras, it has a rounded body, prominent barbels, and an active, social personality. These fish are constantly on the move, sifting through the substrate in small groups, making them both useful and entertaining additions to community aquariums.

Yellowfin Corydoras are hardy, calm, and ideal for aquarists of all experience levels. Their gentle nature and schooling behavior make them especially appealing in planted and natural-style tanks.
