The eel is active and interesting to watch. I placed it in a 75-gallon tank with live rock and a few corals. It didn’t attack the corals, but I keep a close eye on it. Feeding is straightforward with frozen fish food. It’s a good addition to a well-maintained tank.

This eel has become a centerpiece in my aquarium. It’s not aggressive, and it stays near the back wall. I’ve noticed it’s curious and will explore the tank when food is introduced. The only thing I worry about is its interaction with delicate polyps.

It’s a unique species, but I had to adjust my tank setup to avoid any contact with soft corals. It’s not ideal for beginners due to its semi-aggressive nature and size requirements.
