Ball Nems can multiply rapidly, but they aren't like an Aiptasia style infestation. The tend to get here and there, but don't grow to any size that should be a concern. It is however a form of Aiptasia, and with nutrients running rampant, they can get out of hand.
Pseudocorynactis are of the order Corallimorpharia as are Ricordia, Actinodiscus (mushrooms). Aiptasia are Actiniaria, true anemones. Ball tip anemones are not a form of aiptasia.
Ok well from all the pictures I've seen I am fairly certain they are ball nems, aiptasia or not they are starting to spread. Are they harmful to the other life in my tank?
here's a couple. I know they are kinda hard to see but I have those 2 and 5 or 6 more just like it. They aren't causing problems right now. It was just the spread of them that caught my attention
That is a ball anemone, they tend to get in and kill Zoa colonies in my tank. Kind of cool looking, all of mine only open at night. I try to get them out when I can though.
That's what the guy at the LFS told me. He didn't have any in stock though and he said they are not fully reef compatible but that he has had luck with them. I might look into that. I've tried controlling the problem today with aiptasia X but I have left a few alive just to try to measure how fast they spread
Yes. But more so since I was feeding frozen 3-4x a day. Now that I'm no longer doing this I hope to see a reduction in their numbers. Most of them are on the underside and in darker areas of my rock.
I didnt' have any issue with my Copperband nipping at anything else. But I only had softies. I would occasionally turn over a few rocks for him, and he would pick it clean.
