and is it invasive? (item 1)
I'm starting to see little red pieces popping up several place on my LR like I did when I noticed this one for the first time 6 months ago. I was at Fish Den a week or so back and I noticed the same stuff going crazy in one of their frag tanks. I don't mind the one piece in my DT but don't want it every where.
If it turns out it's not something I want to keep in my display would it be any benifit to a broodstock tank?
I'm also wondering if 2 and 3 are the same plant/algae. I thought 2 was the same as 1 but it has taken on the look of being air filled. Harmful?
