I added the Silver Trevally to my 70-gallon reef tank and it has been peaceful and active. It doesn’t bother the corals, though I keep an eye on it. Easy to care for and fits well in the tank.

The fish arrived healthy and has adapted well. I noticed it occasionally brushes against a soft coral, but nothing serious. It’s a good addition to a beginner’s tank.

Perfect for a small reef setup. It’s calm, doesn’t eat the corals, and looks great. I’m happy with the purchase and the species choice.
