Its alot like unsightly nose hair
& I really dont want it in my main tank.. The rock I received from Liverocks.com is covered with little hairs ( for lack of a better description ). Do I scrub them off or leave them. I dont want to smoother the coraline on the rocks and I dont want it dying off and causing a spike... But if its benefical I will leave it?? Any advice??
Act on your impulses.. You'll feel good now & it will give you something to regret later!!
