Care Guide for Marbled Moray Eel

✅ Tank Requirements

• Minimum Tank Size: 250 liters (65 gallons) for juveniles; larger tanks (400L+) for adults

• Aquascape: Provide numerous hiding spots (PVC pipes, rock caves)

• Lighting: Low to moderate – eels prefer dim environments

• Filtration: Powerful filtration to handle high bioload and keep water pristine

• Lid Required: Secure lid essential to prevent escape, as eels are skilled climbers

✅ Water Parameters

• Temperature: 24°C – 28°C (75°F – 82°F)

• pH Level: 7.0 – 8.0

• Salinity: Brackish water preferred (SG: 1.005–1.015), though juveniles can adapt to freshwater temporarily

• Water Changes: Weekly 25–30% to maintain water quality

✅ Feeding Habits

Marbled Moray Eels are strict carnivores and prefer meaty, protein-rich foods.

• Recommended Diet:

  • Fresh or frozen shrimp

  • Squid pieces

  • Fish fillets

  • Earthworms (as an occasional treat)

Feed 2–3 times per week, as eels have a slower metabolism compared to other fish. Use feeding tongs to avoid accidental bites.

✅ Tank Mates

Due to their predatory nature, Marbled Moray Eels should only be housed with large, robust species that they cannot swallow.

Suitable Tank Mates:

• Large brackish or semi-aggressive fish (Scats, Monos, Archerfish)

• Other large, non-aggressive tank mates in properly sized tanks

Avoid small fish, shrimp, or slow species, as they will likely become prey.

✅ Behavior & Compatibility

• Behavior: Nocturnal and secretive, spending most time hiding

• Compatibility: Best kept singly; can cohabitate with large, fast fish in big tanks

• Personality: Intelligent and curious, may become accustomed to hand-feeding with caution
