Freshwater Snake Eel

(Lamnostoma mindora)

The Freshwater Snake Eel is one of the most unusual and hard-to-find eel species seen in the aquarium hobby. Native to parts of Southeast Asia, Lamnostoma mindora is known for its long, slender body and secretive behavior. Very little is still known about this species in captivity, which makes it especially interesting to experienced fishkeepers.

These eels spend much of their time buried in sand or hiding beneath wood and rocks. They are mostly active at night and tend to be shy when first introduced to an aquarium.
