The convict tang arrived healthy and active. It’s peaceful and doesn’t bother other fish in the tank. I’ve had it for three months now and it’s thriving in a 75-gallon reef tank. Easy to maintain with proper water parameters.

It’s a nice addition to my reef setup. The fish is calm and doesn’t chase other species. I noticed it’s active during the day and spends time near the back wall. Feeding is straightforward with flakes and spirulina.

Great quality and well-packaged. The fish is vibrant and shows good coloration. It’s been two months in the tank and still active. I appreciate the clear care instructions included.
