The tiny Atlantic Blue Tang arrived healthy and active. It’s been two months in my 75-gallon tank and has grown steadily. The fish is peaceful and doesn’t bother other tank mates. I appreciate the clear labeling and accurate description.

This fish is a great addition to a reef tank. It’s active and colorful, and it’s not aggressive. I’ve kept it for three months now and it’s thriving. The only thing is it needs a larger tank to grow properly.

I bought this as a starter fish for my intermediate reef setup. It’s been very calm and doesn’t eat corals. The size is small when first received, but it’s growing well. Very satisfied with the purchase.
