Got this fish for my 50-gallon reef tank. It’s active and colorful, though it does show aggression toward smaller fish. I’ve had to remove a few species that were too slow-moving. Still, it adds a lot of visual interest and is a good choice for beginners with proper tank setup.

The fish arrived healthy and looks vibrant. I’m cautious about introducing new tank mates. It’s not the most peaceful fish, but it’s a striking addition to the reef. I recommend a large tank and careful selection of compatible species.

Perfect for a beginner reef setup. The fish is bold and active, and it’s easy to spot in the tank. I made sure my tank was at least 50 gallons and avoided small, slow fish. It’s a great centerpiece for a reef display.
