I’ve kept this eel for over a year in a 100-gallon tank with a well-established reef. It’s calm most of the time, but I’ve noticed it occasionally nips at soft corals. I keep a close eye on it and maintain strong water flow. It’s a challenging but rewarding addition to an expert aquarium.

The eel arrived healthy and has grown steadily to 22 inches. I’m cautious about its placement and keep it in a corner with strong current. It doesn’t eat much, but it’s active during the day. Not for beginners, but worth the effort.

I expected more aggression, but it’s actually quite passive. Still, I had to remove a small soft coral after a few weeks. I’m learning to manage its behavior better with proper tank layout and hiding spots.
