ID this purple branchy thing please :)

I have these purple branch type things growing on this rock with my GSP ... I know I have a few vermetid snails but these look different.. just wondering what they are. Thanks.

Looks like thin branching coraline.

Is that how ochtodes starts?

Nifty... well.. they’re pretty.. small now but spreading ... the GSP will probably overrun them.. hah

Looks like my snails or grazing fish ate them.... well, the snails were nearby and a bunch of them are gone now..

All I found out what this stuff is.. I think.. Galaxaura Marine Macro Algae or also called Horsetail Coraline Macro Algae... It's been growing.. (and yes I have some bubble algae I need to prune)
