Got this fish for a beginner setup, but it was aggressive and scared away smaller fish. Tank is now 150 gallons and I’ve removed sensitive species. It’s a bold choice and not for a mixed community.

Purchased for a larger tank. The fish is active and visible, though it does chase other fish. Works well in a spacious setup with no corals. Good for experienced hobbyists who know the risks.
Sophie Parsons –
Expected a calm fish, but this one is very territorial. It attacked a small shrimp and I had to remove it. Not recommended for small tanks or mixed communities.
