The rosy loach is a small nano tank species perfect with exotic fish and rasboras. These Chinese loaches are very small and have a light pink and brown color. Rosy loaches are wild caught in small streams in China and uncommon in the aquarium hobby. In the wild and in the fish tank rosy loaches prefer to swim in packs and will adapt to flake food that floats to the bottom. These loaches are ideal for natural planted aquariums and they love to run around the leaves.
