Hello I was just wondering if this purple spots were corraline growing on my rocks, or maybe it’s caynobactria?? My tank is about a month and a half old so ignore the green algae please, still trying to work out the lighting schedule. Also was wondering what these small blackish dots were? Any ideas?
I recently put in a coral, whose base has a ton of corraline as well as some snails with corraline.
