this stuff actually looks not to bad. very short kinda fuzzy deep red algae. my scopas tang was eating it but died a day after i got him. im just curious what it is. maybe get a hold of it before it gets real bad. maybe its a good algae? is my first saltwater tank and at first i thought it was coraline growth. it doesnt seem to mind high flow since it is also starting to grow on my power head. any ideas?
