The fish arrived healthy and active. It has adapted well to our 120-gallon tank. We feed it algae wafers and flakes daily. It swims vigorously and adds a lot of color to the tank. Easy to care for once the water parameters are stable.

We’ve had this tang for three months now. It’s active and shows no signs of stress. The size is within the expected range. We recommend pairing it with non-aggressive fish like clownfish or gobies.

Great addition to our reef tank. The yellow fins stand out beautifully. Water quality has been stable, and the fish is eating well. We’ve adjusted the flow slightly to match its swimming pattern.
