Dwarf Moray Eel (Gymnothorax melatremus)
The Dwarf Moray Eel is a small species of moray eel, typically reaching a maximum length of about 12 inches. It has a whitish-yellow body with a lighter belly, often featuring a light brown dusting or faint speckled pattern. A distinctive feature is its pale blue ‘cat eyes’ that add to its attractive appearance.
This eel requires a well-established aquarium of at least 60 gallons with strong filtration. An efficient protein skimmer is highly recommended due to the high waste production from its carnivorous diet. The tank should be densely stocked with live rock of various shapes and sizes to provide hiding places and natural complexity.

The Dwarf Moray Eel is a striking addition to my 80-gallon tank. Its pale blue eyes and speckled pattern stand out. I’ve maintained strong filtration and added plenty of live rock. It’s active but not aggressive, and it hides well during the day. A beautiful and unique species.

I was drawn to the eel’s appearance, especially the cat eyes. The tank has been stable for over six months now. I use a protein skimmer and keep the water parameters tight. It’s a peaceful resident and doesn’t cause much disturbance.

The eel arrived healthy and has adapted well to the tank. The coloration is exactly as described—light yellow with subtle brown spots. It’s curious but not overly active. The live rock setup has provided plenty of shelter, which it uses frequently.
