Sally Graham –
The Goldentail Moray Eel is a stunning addition to my 200-gallon tank. It’s active and curious, and the golden tail stands out beautifully. I’ve provided plenty of caves and rockwork, and it seems comfortable. Only recommend for experienced aquarists with large tanks.
Sally Morgan –
It’s a unique and eye-catching eel. After a few weeks, it started exploring the tank more and even interacted with a larger fish. I made sure the water parameters were stable and the tank had good flow. Still cautious about keeping it with smaller species.

The eel looks impressive, but it’s been a bit shy and doesn’t seem to explore much. I think it might need more hiding spots or a larger tank. Overall, it’s a good choice if you’re prepared for a long-term commitment.
