Local Muong beliefs attribute the health and safety of the village to the well-being of the fish.
The spring is situated at the base of the Truong Sinh limestone mountain, which features extensive cave networks.

Cam Luong Mystic Fountain, known locally as Suối Cá Thần, is a natural spring at the foot of Truong Sinh Mountain in Thanh Hoa, Vietnam. The limestone cavern system hosts a massive population of the 'zodiac' fish, specifically the species Spinibarbus denticulatus. These fish, considered sacred by the local Muong ethnic community, reach weights of up to 30 kilograms each. The spring water flows directly from the mountain cave and maintains a clear, constant volume year-round. Local legend forbids visitors from catching or consuming the fish due to their protected, spiritual status. The stream spans approximately 100 meters in length and flows into the Ma River basin. The area is a protected natural monument managed by the local provincial authorities. The site serves as both a biological curiosity and a cultural focal point for Muong traditional customs.
