Yellow-Edged Moray Eel
The Yellow Edged Moray Eel is a larger species of Moray Eel that can attain lengths up to 8 feet as a mature adult. Younger or smaller-sized Yellow Edged Eels are primarily brown to purple in color with its namesake yellow edge or border running along the perimeter of their fin. As the Yellow-Edge Eel matures, the overall body color becomes more mottled with an attractive creamy yellow-gold coloration.
This eel requires an established aquarium of 300 gallons or larger, with very strong filtration. An efficient protein skimmer is highly recommended due to the high waste production from its carnivorous diet. Aquascape liberally with live rock of varying shapes and sizes to create a network of caves, crevices, and tunnels for the eel to hide and navigate.

The eel has been in our 400-gallon tank for six months and is very active. It uses the rock crevices well and seems healthy. The yellow-gold coloration is striking when the light hits it. We’ve had to increase our skimmer usage, but it’s worth it for the visual appeal.
Trevor Turner –
We followed the setup guide carefully with live rock and strong filtration. The eel is calm and hides in the caves during the day. It’s a beautiful addition to our reef tank, though it does require a lot of maintenance.

After a few weeks, the eel started exploring the tank and even moved into a new crevice. The color change from purple to yellow-gold is impressive. We’re happy with the long-term stability and appearance.
