Received the fish as described. The eye area is clearly visible and matches the expected markings. It’s aggressive but well-suited to a large tank. Only recommended for experienced aquarists with a 250+ gallon setup.

The fish arrived in good condition and looks exactly like the photo. I was concerned about misidentification, but the clear eye area confirms it’s a Yellow Margin Triggerfish. Aggressive behavior is expected, and it’s not for beginners.

It’s a solid purchase with accurate markings. The tank size is large, and I’m managing the aggression with proper tank layout. Would not recommend for smaller setups or reef tanks.
