I added the Filamented Sand Eel to my 75-gallon reef tank after researching compatibility. It has been calm and active in the sand bed. I noticed it occasionally nudges smaller polyps, so I’ve increased the spacing of soft corals. Overall, it fits well in the system with proper monitoring.

The eel has adapted well to the tank. I keep an eye on it during feeding times, as it tends to be more active then. It doesn’t harm the main corals, but I’ve moved a few delicate colonies to safer areas. Good for intermediate reef keepers.

It’s not the most active fish, but it’s present and doesn’t cause issues. I’m still adjusting the tank layout to avoid direct contact with fragile corals. Works okay in a larger tank with good flow.
