✨A rare catfish endemic to Lake Biwa—the native Japanese species "Iwatoko catfish"✨

The Iwatoko catfish

is a rare catfish known as an endemic species that inhabits only Lake Biwa, Japan's largest lake.

It is characterized by its taller body than typical catfish, its slightly rounded body shape, and its subdued grayish-brown coloration.

In the wild, they inhabit the rocky areas and deep waters of Lake Biwa, and their leisurely swimming along the bottom has a unique and dignified appearance.

As ornamental fish, they are not widely available, making them highly popular among aquarists who prefer native Japanese fish.

Difficulty of keeping: Intermediate level.

This is a hardy fish, but it grows large, so a spacious tank environment is necessary.

Since it is nocturnal, providing hiding places such as driftwood and rocks will help keep it calm.

The Iwatoko catfish, a native species, offers a unique, understated charm and presence.

Because it's a species with limited availability, this is a great opportunity for anyone who's been curious about it. ✨
