cyphastrea colour change

[Moort82]

Have a weird mottling going on, on a cyphastrea. I'm not sure whether this is a lighting issue, as in too much or not enough so wondered if anyone had a similar experience or new what was going on.
My initial thought was too much light as its growing strongly and the underside, being shaded, is still the true colour. The shop seemed to have it only under 2 blue T5's so not a great deal of lighting.

TIA

If it's fairly new it may be regaining it's original color, i've seen favia "painted" like that but not cyphastrea. I don't know how long you've had it in the tank, i know my lps in my tank seem to take 100x longer to regain their original colors after bleaching or darkening than the sps in there. That last pick looks like the type that pacific east sells, black cherry i think they call it.

Thanks. Its something that has happened in the tank as it was the chocolate brown when I was given it. Had it since april and it has grown pretty well but the silvering has increased in that time. I have it at the back as its not really my thing, so don't keep a close eye on it, but don't think it has worsened over the last couple of months and it was quite quick to change when it did. I thought I had just put it in too bright a spot and would leave it but there has been no real improvement. I'd say it was unhappy if it hadn't grown so much. So who knows?

If its darkening in color it's not too much light i would think. If it's growing i would just leave it alone and see how it turns out. If it were receding then you would have an issue.

Its the silvering that is the issue as the dark brown colour is the natural colour. So I don't think it is too much light either but equally it hasn't been bleached so its a little bizarre hence my confusion.
Don't know whether it is a common issue with cyphastrea and whether it is solvable. I'm tempted to chop it and place different part in different conditions to see what happens. Equally may give it a dip (although not thinking there is actually anything wrong with it) just to see how that affects it.
