What Is a Tiger Moray Freshwater Eel?
The Tiger Moray Eel, also known as Gymnothorax tile, is a unique and misunderstood species often sold as a freshwater moray eel. While technically a brackish water eel, it can live in freshwater short-term, but thrives long-term in lightly salted environments. Its banded pattern and snake-like movements make it a showpiece in any predatory or exotic tank.

💡 Can Tiger Morays Live in Freshwater?

Salinity: 1.005–1.010 (marine salt mix)
-
Temperature: 75–82°F
-
pH: 7.5–8.5
-
Ammonia/Nitrites: 0 ppm
🧪 Tip: Use a refractometer or hydrometer to maintain consistent salinity.
