Gymnothorax polyuranodon

The Freshwater Moray Eel is a beautiful, large, and snake-like fish with a striking pattern of gold or leopard-like spots, which is why it's also called the Tiger or Goldspotted Moray. Despite its name, this is not a true freshwater fish; it must be kept in brackish water, which is a mix of fresh and saltwater, to stay healthy. Keeping one is a serious, long-term commitment, as they can live for over a decade and grow quite large, requiring a very spacious aquarium of at least 450 litres.

This eel is a predator that should be housed alone. It will eat any fish or shrimp small enough to fit in its mouth. They are not active swimmers, preferring to spend most of their time hiding in caves or pipes with just their head poking out, waiting for food. You'll only need to feed it meaty foods like shrimp or pieces of fish about once a week. Be very careful with your aquarium lid! These eels are notorious escape artists and can squeeze through the smallest gaps. Because of their specific water needs, large size, and predatory nature, they are considered difficult to care for and are only recommended for experienced fish keepers.
