At the moment I dont have a picture to show so Im hoping someone can give me a place to start with and Id on this. Last night while cleaning my tank I noticed new growth on some of my rock. They are approximately 1/4" oblong and tan/brown color in the center. The outer part is a dark burgundy almost purple color and is fuzzy looking. Im assuming its from the live rock in my tank even though its growing on the dead rock. Any idea where to start with an id. Im assuming a type of algae but really have no clue
