Acro changing from brown to solid green?

[Saisori]

This is a needle in hay stac acro. Recently changed to green coloration. Read could be light related. Running ap700 about 10inch off water level at 50% peak for 2 hours. Mostly blues on the controller. Any other causes?

Do you see polyps and skin on it? If not, it may be algae forming over the skeleton.

Hard to tell in the photo.

Coral, acros especially, will adjust and change colors, shape, etc. as they acclimate. That tank looks pretty new also......could just be a maturation issue. I would just leave it where it is, and keep an eye on it.

I've never seen polyps for this acro. If algae, would it be strange to only form on a single piece of acro?

Edit: sorry about photo, late night picture looking for pest.

Thanks I will continue to keep an eye on it. The tanks been running for 7 months now, hopefully everything will start to get back into swing. It just this acro that change the others in the picture are doing well and the ones in the back are starting to encrust over their plugs.

Green coloration isnt a bad thing at all (better than brown). You mentioned the lights being at "peak" for two hours though; what exactly do you mean? Are the lights only on for two hours? Not long enough if so.

it really does look like a skeleton with algae growing on it. The reason it would only be on one acro is because that acro is dead and has no flesh on it. it's literally a skeleton with algae growing on it. Of course better pics can confirm but this appears to be dead.

Sorry, what I mean is the lights ramp up to 50% intensity and stay at that level for 2 hours. I run them around 10 hours long.

Like others have said, it looks like algae on a skeleton but it's hard to tell in the picture. Does the green fluoresce under blue light? When I first added SPS to my current system they were brown at first...after acclimating over several weeks every single one turned fluorescent green before (very) slowly shifting to their individual colors. I did a lot of reading during that time and apparently has something to do with zooxanthellae adapting to new light spectra
