One of the only species of Moray Eels to inhabit true freshwater environments, the Tiger Moray (G. polyuranodon) is a rarity in the hobby due to the remote areas it inhabits in West Papua, Indonesia. A hardy and adaptable fish, it can tolerate freshwater to almost full strength marine conditions if acclimated carefully. In the wild, they feed primarily on crustaceans and small fish, and like most Morays tong feeding is often the best way to get them used to frozen foods. They are a remarkable escape artist and any tank housing these fish should be completely escape-proof.
These eels are native to Indonesia and are one of the easiest fish to take care of. They will eat just about anything. A very active eel and will generally find a hiding place with it's head poking out but will be seen swimming around the tank often during both night and day.
