Freshwater Moray (Gymnothorax polyuranodon) is a true moray eel for advanced keepers, not a spiny eel. It needs a large covered aquarium, cave networks, stable mineral-rich water and tank mates too large to swallow. Plan the setup around the eel first, because escape prevention and feeding control matter every day.
| Scientific name | Gymnothorax polyuranodon |
|---|---|
| Adult size | Large; plan for 60-100 cm over time |
| Minimum aquarium | 500 litres or larger for long-term care |
| Temperature | 24-28 C |
| pH | 7.0-8.2 |
| Temperament | Predatory but often shy; will eat fish small enough to swallow |
| Diet | Carnivore; prawns, mussel, fish strips, earthworms and other meaty foods |
Build the aquarium around security and shelter: heavy lids, covered pipe gaps, stable rockwork, caves and smooth routes for the moray to patrol. Freshwater Morays are often sold for freshwater aquariums, but they are euryhaline fish, so use mineral-rich freshwater to lightly brackish conditions and avoid sudden changes.
Keep stocking light. Suitable companions must be robust, calm and too large to swallow. Small fish, ornamental shrimp and delicate slow feeders are not safe choices.
Offer meaty foods such as prawn, mussel, earthworm and fish strips. Feed with tongs where helpful, remove leftovers and avoid feeder fish, which can introduce disease and poor nutrition.
Livestock orders are packed carefully and sent by licensed live-animal courier. The Live Arrival Guarantee applies when the receiving and acclimation instructions are followed.
