Coraline or similar?

[SlugSnorter]

PICS COMING SOON

I have an interesting coraline or something similar, its dark, and hardened, comes in smaller starting specs than the "normal" pink coraline patches in my display. Its a deep blue, and comes in typically speckled small groups.

There is a type of coralline that is blue (and many other colors actually). I've read it usually grows in lower light than our traditional purple/pink, but I have absolutely no experience with it. From what I understand it's fairly uncommon.

Interested, waiting for pics...

My rocks are encrusted with dull kinda pinkish, dark brown/red, and brighter purple (I think,,, color blind).

Only coralline on my glass so far is the "normal" pink you mentioned (that starts as small patches).
