Aquarium Advice FINatic
I kind of asked this question in another thread before but didn't get much response so I thought I would try again. I have a zoanthid frag that has started to grow some sort of algae on it. Looks like fine hair or thread. It's sitting on some rocks and now the algae has migrated to the rocks. Anyone know what this is and should I be concerned about getting rid of it ???
