Clowns and bubble coral

[Coralgurl]

Well the nem I picked up last nite, I posted pics on another forum I use and was told that it's bleached as it's whitish yellow and needs go be nursed back to health. It's a sebae nem with purple tips. The store had 2 diff colors, one more beige and we liked this one cuz it was brighter and wasn't told it was unhealthy. Was at another lfs last week and saw the same ones, same color. I have 2 t5s white and blue and vertex LEDs white and blue. My corals are all growing. Do I have a problem with this nem??
