Added the Blacksaddle Filefish to my 30-gallon reef tank after researching compatibility. It’s active and doesn’t harm the corals. Feeds well on small crustaceans and has settled into a calm routine. Good for intermediate aquarists.

The fish arrived healthy and fits well in my tank. It’s not overly aggressive, but I keep it away from small shrimp. Needs a bit of space and a stable environment to thrive.

I’ve had this filefish for six months now. It’s become a regular part of the tank community. No issues with corals or other fish. The size is within the expected range and it looks vibrant.
