So I got my first zoanthid about 2 weeks ago. Well, it doesn't seem to be blooming. At one point, it was extending out quite far but still would not bloom. The lady at my LFS said that they maybe growing algae which irrates them and that I should lightly brush them with a very soft toothbrush. Well, I did that about 5 days ago and now they seem more ****** than anything. They are pretty high in my tank and a moderate flow area. Any ideas?
