I have this kinda odd algae starting to grow over my rocks and corals. It's kinda fibrous, white / grey color. I'm treating with fluconazole in case it's a type of bryopsis but I'm really not sure. Any help is appreciated.
Don't think they're hydroids, but I could be wrong. It's tough to see in the pic but they appear to be some type of plant matter. They don't move or act like a critter when they're touched.
