View Full Version : Red fuzzy algae - ID please

I have this algae growing in a refugium in a large reef system that I manage. Since it took a hold up there, it has managed to outcompete dragons breath and chaetomorpha. Does anyone know what the species is? It grows loosely attached or as a tumbleweed. The tangs prohibit it from growing in the display but it is very persistent in the 'fuge. The resident pink decorator urchin ignores it.

It looks like red turf algae, but in the third picture I can see the shape of a leaf, which points to it being some sort of red macro. I haven't really seen anything like it before.

The third picture is the first time I've seen it as a branched growth. It is nearly always in little cotton ball - like tufts. It remains a short red mat where grazers keep it cropped. Trochus snails eat a little but must not like it - they move on.

Agreed. If it is then turbo snails will take care of it.
