The eel is impressive in size and presence. It dominates the tank and draws attention. I’ve kept it in a 125-gallon tank with some robust corals, and it hasn’t damaged them. It’s aggressive but not overly so. Great for a statement piece.

First time keeping a large eel. It’s active and curious. I made sure to keep it in a spacious tank with no small fish. It’s not shy, but it doesn’t attack regularly. A bold choice, and it’s worth it for the visual impact.

Ordered the large size and received a healthy specimen. The eel is calm when not feeding and shows interest in the environment. I’ve taken photos and shared them with the store. A great addition to a larger aquarium.
