Mary Newman –
Added a male Pintail Fairy Wrasse to my 100-gallon reef tank. The colors are vivid and it’s very active. It’s peaceful and doesn’t bother other fish. Feeds well on copepods and small crustaceans. Great addition to a mature reef setup.

The fish arrived healthy and has been swimming well in my 75-gallon tank. It’s active and shows off its tail beautifully. I’ve noticed it grazing on the live rock. A bit shy at first but settled in after a few weeks.

Perfect for a reef tank with a good flow. The male is stunning with its long tail. It’s not aggressive and doesn’t chase other fish. I’ve kept it alone and it’s thriving.
