Tiger Moray Eel

The Tiger Moray Eel has a striking spotted pattern and a secretive, shelter-oriented way of life. This unusual moray is associated with freshwater and estuarine habitats and rewards careful planning, secure housing, and patient feeding rather than a typical small community setup.

Fish details

• Scientific name: Gymnothorax polyuranodon
• Size offered: 25–30 cm or 35–40 cm
• Adult size: Potentially around 150 cm; a major long-term housing commitment
• Origin: Indo-West Pacific river and estuary systems
• Water type: Freshwater to brackish; confirm the current holding salinity before acclimation
• Temperament: Predatory, often shy while settling

Recommended aquarium conditions

• Aquarium: A very large, securely covered system with enough floor space for the adult to turn comfortably; discuss permanent housing before purchase
• Temperature: 24–28°C (75–82°F)
• pH: Approximately 7.5–8.0 in a freshwater setup; keep chemistry stable

Create several smooth caves or sturdy pipe shelters large enough for the whole eel. Secure rockwork and use efficient filtration with good oxygenation. Morays can squeeze through surprisingly small gaps, so protect filter openings and seal the top carefully while maintaining ventilation.

Diet and feeding

Offer suitably sized thawed shrimp, fish, and other aquatic meaty foods using long feeding tongs or a feeding stick. Target-feed in subdued light and allow time for a new arrival to respond. Keep hands away from the mouth and confirm its established feeding routine with the store.

Compatibility and care

Any fish or invertebrate small enough to swallow is at risk. Choose calm, substantial companions only after checking compatibility, and avoid crowded feeding situations. This species differs from other morays sold under vague freshwater labels, so do not apply its requirements to every moray. Make salinity changes only through a planned, gradual acclimation process. Clean water and a secure enclosure are essential throughout its life.
