So to you once again my esteemed, knowledgeable, fellow aquarists, I ask, should I be concerned about this brown stuff on my giant zoanthid and/or the hairy/grassy stuff hiding underneath (which I only just noticed after taking this pic). The zoa seems healthy enough, but I want to be pro-active if necessary.
As always, thanks for your time and knowledge... :)
