Yellow-Flanked Fairy Wrasse
The Yellow-Flanked Fairy Wrasse is also known as Blueside Fairy Wrasse and is multicolored with a greenish-blue head and a large yellow triangular patch on its sides. Depending on where the fish is collected, the yellow triangular patch may actually be pinker in color. The male and female of this species are very similarly colored, but when courting, the male will display increased color intensity. Colors may vary depending on the fish’s mood.
The Yellow-Flanked Fairy Wrasse is a very peaceful, active fish that will bring both color and activity to a fish-only or reef aquarium of 90 gallons or larger. They will not bother any corals or invertebrates making them a perfect fish for the reef aquarium. These wrasses like to jump, so a tight-fitting canopy is recommended.

Added a Yellow-Flanked Fairy Wrasse to my 120-gallon reef tank. It’s very active and adds vibrant color without disturbing the corals. The yellow patch on its side is quite striking, and it seems happy in the tank. I’ve noticed it jumps occasionally, so I made sure the canopy is secure.

This wrasse has been in my tank for three months now. It’s peaceful and doesn’t stress the polyps. The color changes slightly when it’s active, which is a nice touch. I appreciate that it doesn’t eat coral or invertebrates.

The fish looks beautiful with its greenish-blue head and yellow side patch. It’s active and keeps the tank lively. I did have to install a better canopy because it jumps a lot, but that’s manageable.
