Gastrodermus hastatus Gold – Rare Golden Dwarf Corydoras

Gastrodermus hastatus Gold is a rare and beautiful golden variant of the well-known dwarf Corydoras species, admired for its delicate appearance, peaceful temperament, and active schooling behavior. This fish is especially popular among aquarists who enjoy nano fish and planted aquariums because of its small size and gentle personality.

Unlike many other Corydoras species that stay strictly at the bottom of the tank, Gastrodermus hastatus is known for its unique swimming behavior. It often moves in small groups and may swim in the midwater level of the aquarium, similar to small schooling fish. This behavior makes them very interesting to watch and adds lively movement throughout the tank.

The Gold variant features a soft golden or yellowish body tone that stands out beautifully under aquarium lighting. When kept in a well-planted tank with dark substrate, their golden color becomes even more noticeable.

Gastrodermus hastatus Gold are peaceful, social fish that thrive in groups and do best when kept with other calm species. Because of their small size and gentle nature, they are perfect for nano aquariums, shrimp-safe community tanks, and planted aquascapes.
