Can Coraline DO THAT??

[kcandcritters]

I have a really nice peice of live rock that is covered in coraline algea and a few small polyps. Over the past week I noticed the algea was starting to cover the polyp and before I knew it... no more polyp! Will coraline destroy anything it gets close to? Should I keep my corals and polyps away from rocks with coraline algea on them?

No that sounds odd...
Sound slike you had other issues... Unless you cann see the polops under it? Can you ? Can't really tell from the pic where to look...

Where! Circle it with a image editing program!

I agree. Too hard to tell what's going on from the pics. I was hoping they were before and after images Circling the problem area would be good, but from the look of the pic, I don't see any coraline growth on the face of that rock. I do see what look like they might be dead polyps?

Yea well, DORKY me sent the wrong pic! And twice at that!
Here's a pic of the rock before... now the mushroom is completly covered and unrecognizable. It's just a lump of purple resembling the rock. Sorry about the quality of the pic. It was the only close up I had of the rock.
Thanks!!

Try to shoot your pix at a higher resolution if your camera is capable.....

I have coralline covered Lr and it has never taken over a coral??? I would say the coral was on its way out and that is why it happened.
How long have you had the coral/LR.
