All the articles I've read have been focused on the microscopic structure, taxonomy and ecology, nothing about aquariums. So again I have no clue. It is a form of coralline so....

It’s hard to snap off a piece but the sandbed has some of its crumbs that fell off. The edges aren’t white. On some rock it looks like something scraped a tiny patch off, so something might be eating it.

Lobophora????

The color doesn't quite match. At first It looks more like the rock is being painted red as opposed to something growing on top of it. The little plates started to appear 1-2 weeks ago.

I've had lobophora, it was brownish and would plate out (thin slimy looking stuff). This stuff looks burgundy in color and almost fuzzy in texture

Here are some older pics in whiter light.

@KJ
Got any thoughts?

Haha sorry. I just came back from a trip to bali and my cellphone is full of vacation pics. Here is a better one.

I agree, the most recent pics show protruding growths similar to lopophora. On the other hand it spread really quickly from rock to rock, mostly horizontally not vertically.

Peyssonnelia perhaps? I have a red algae that can grow very fast if I don’t keep nitrates around 5-8. I hate the stuff as the SPS have to clear it off the rock as they encrust.

It's crazy how close to lobophora that seems! New one for me.

Really a toss up! I went searching to see if I could find something that would really chow down on it. Snails, urchins, crabs nibble but no one chowing down.

I agree the closest thing to it was peyssonelia. My nitrates are around 10, usually keep them around there with weekly water changes. Maybe I have to go lower than that.

I think my emerald crab eats tiny bits here and there. True, I’ve tried all different types of algae eaters no one really likes it.

There is definitely another trigger at play. I see more growth on new rock (dry) than I see on the old live rock that I have had for years. The lack of a good bacterial film seems to give it an advantage.

I agree. It’s definitely growing faster on newer rock. It even out grows the coralline to a certain point. I also noticed that it grows low independent of light.
