Hey All,

I added a frag to my tank and have noticed some questionable algae. Can you please help me ID. I will share 3 different patches of Algae so an ID on each one would be helpful. To me pictures 1 and 2 look like Bryopsis and possibly 3 as well. If so, should I be removing the frag and purchasing Flucanzole? Do I scrub the frags and treat with Hydrogen Peroxide where the algae was?

Any help is appreciated! I'm not sure how could get the algae off of the zoa frag. It seems to be pretty in with the frag itself.

Yup I read through that thread, seems super helpful. Just want to make sure it is Bryopsis and not just green hair algae.

Hair algae is like strands of hair that dissolve into a mush in your hands when lifted out of the water. While there are different types of Bryopsis, each strand will be feather or fern tipped in appearance and the stem will retain some of its structure out of water. Your second picture looks like a feather to me. The stem looks sturdy and defined. Of course, there are a lot of different types of algae out there, so could it be something else? Sure. A sample under a microscope would give the experts here a better look-see, but Bryopsis is my best guess based on the pictures you've provided. Bryopsis was once thought of as an incurable scourge in our tanks, but Flucanazole has turned that around and it is now controllable, even curable.

Good luck with the battle! I remember it well!
