Received the Devil’s Lionfish in good condition. It’s active and colorful. I’ve kept it in a 50-gallon tank with some corals, and it hasn’t harmed them. Just watch for aggressive behavior toward smaller fish. Overall, a great addition to a reef tank with proper care.

The fish arrived healthy and looks vibrant. I’m a beginner and followed the care guide. It’s semi-aggressive but not overly so. I’ve noticed it hides during the day and comes out at night. Works well in my setup.

Great choice for a beginner. The lionfish is active and visually striking. I’ve maintained a 50-gallon tank with live rock and corals. It coexists peacefully with most species, though I removed a small shrimp that got too close.
