Why is my star polyp coral white?

[briareos]

After 3 weeks closed up in my tank, it opened, but the polyps were all white.

And that's the way it has been for the past 3 weeks. But the thing is, even though it's white, the pink mat is spreading.

How can I get the color back? Is it even possible?

seems like it bleaching... i have notice one of my clove polyp also change to white colour but not the entire colony.. the rest is doing quite well.

i just got a star polyps yesterday night and waited for the whole night only about 8 polyps open...

did you do any changes to your tank before they close for 3 wks?

maybe you can place it at a place with up to moderate current flow and good lightning?

what is your water parameters?

I observed that the pink mat spreading material is the colonising of the poly stars...for mine, the new "borns" are white until they grow older...however, have not encounter bleaching of stars regardless placed in high or low flow...depth of water too. (2ft Nano tank). Have you check you water parameters...btw wat type of light are you using?
