I did some research and found out that this is a calcium based algae. I guess its pretty harmless. I have no idea how I got it, it just popped up. Has anyone else dealt with these guys before? They don't bother me as long as they are harmless. They are kinda cool looking.
well maybe we can meet up at a swap one day and i can snag a small piece from you guys. i have a tank dedicated to SW macros and would love to add it to my collection one day.
