An algae on my rock that I thought was cool at first, has now turned into a problem of some sort. It seems to be slowly spreading and replacing coralline algae. It may be " Lobophora variegata ". From what I have read, an urchin, foxface or some tangs like the naso or kole could help me out. The problem is that urchins bulldoze stuff around, I'm not a fan of poisonous pets like the foxface and the naso should be in a bigger tank than my 90. I have a 2" Hippo tang and he ofcourse is not the correct tang type to help me out. I really do not want to dismantle my tank to scrub this crap either. Any other options here?
