Strange pink coralline (very rare in tanks) - what is it?

[ReefDream]

I have this stuff in one place in my tank. In all my years of keeping reefs and looking at them, I never saw it before. It is some sort of coralline I believe, and it doesn't grow hardly at all (as in an inch over a year or so). What is it?

thats awesome if its coraline.

It is hard overall, but if you scrape it with your fingernail, the little hairs break off and crumble easily. I could destroy the entire mass with little effort, but I don't want to.

I had some of that on some of my Fiji rock back in about 98-99, was pretty neat. It never got out of control, just kind of grew laterally, if you know what I mean. It never got long, just spread out.

Definatly coraline looks alot like the coraline found growing in temperate rock pool well at least the ones I have seen in england.
Obviously a different species but defo coraline
beautiful as well

It should almost feel like a brillo pad to the touch, not very soft at all.

WorldNation, I don't have enough to sell it. It would never make it anyway. If it grew well, it'd spread faster than a inch or so a year. It only grows in my tank in a single area about 2"x2". That area has very low current and relatively low light (but I have a very bright tank overall).

Matt, it does feel like a brillo pad. Did yours live for long?

ReefDream, I have a few tiny bits of purple branching coralline, similar to what you have. Only my pieces are much smaller than what you're showing here.
