shoe_465 Posted January 20, 2005 Share Posted January 20, 2005 My rocks have been changing color lately which i found was normal as a tank matures but this purple stuff has been growing on them, not sure if it is a type of algae or maybe a coral perhaps. Link to comment
jenniebutterfly Posted January 20, 2005 Share Posted January 20, 2005 looks a lot like coraline. does it rub off? if it does than it is probably cyanobacteria Link to comment
