i have this brown leafy algea, that iam pretty sure is lobophora. in researching it, it seems like there are only two ways to get rid of it......cooking your rock - not an option, or a naso tang. been looking for a naso small enuf to match my other fish but no luck, plus my 90g is probally a little to small for one anyway, and with my luck it wouldnt eat it anyway. so does anyone know of any other options?
