Horge,
Thank you for your response. I don't have any other pictures, and my lawnmower blenny has pretty much taken care of all the algae. From what i remember, the long strands that were anchored on the rocks and glass came from a small base and if I remember correctly, 3 strands came out of the base. The algae also grew out of the sand bed. Are these characteristics of bryopsis plumosa?
Thank you again for your response.
Ryan
