Brown star polyp

[freybizzy]

My yellow star polyp that I bought two days ago has a really nasty brown coloration right now. It was brilliantly yellow at the store, what could have caused this? Is it just acclimating or is something wrong?

What lighting are you using?

They are not star polyps. They look like these-
Saltwater Aquarium Corals for Marine Reef Aquariums: Colony Polyp, Yellow
And lighting won't have an effect that fast. I'm guessing the lighting they were under was better.....like LED with a lot of blue maybe...

Either that or the op is using cfl type lighting was what I was thinking

I agree with X
that there yellow polyps
Lighting also would change the appearance / Color
