The Noronha Wrasse is very active and adds a lot of energy to the tank. It started cleaning other fish after a few weeks, which was a pleasant surprise. The colors are vivid and it seems to enjoy the feeding schedule. Only issue is it jumps, so a secure lid is essential.

Great addition to a reef tank. The fish is colorful and curious. It spends most of its time near the live rock and occasionally swims through the open water. Feeding it daily with brine shrimp and mysis keeps it healthy and bright.

Very happy with this wrasse. It has been in the tank for three months and still shows strong coloration. The cleaning behavior is natural and helps keep other fish healthy. The only thing to note is the need for a secure lid.
