The theme for this month's contest is: Algae Patina

This one is going to be tough but I hope some of you take up the challenge. There is a fine line between algae on an object that makes it look natural and old (patina) and algae on an object that simply makes it look unkept and dirty.
Who can strike that balance best??
Please take a picture of algae patina in your aquarium. Be as artistic and creative as you like.
The rules:
