I’ve had my Blacksaddle Filefish for three months now. It’s active and stays in the rock crevices without causing any issues. The tank is 40 gallons and has a mix of corals and invertebrates. It’s not overly aggressive, just curious and clean. Good choice for intermediate reef keepers.

The fish arrived healthy and has adapted well. It’s not the most colorful, but it’s peaceful and doesn’t bother other fish. I appreciate that it’s reef-safe. A solid pick for a mid-level tank.

I added this filefish to my 35-gallon tank with a mix of soft corals. It’s been active and doesn’t seem to eat much. It’s not aggressive, just watches the surroundings. Very satisfied with the purchase.
