The second one is not a rock anemone, but I'm not sure what it is. It looks like Lobophora in growth pattern, but maybe it is a sponge. You do know there is an Aiptasia below it though, right?

I looked up Halimeda and researched it on ReefAquaria once Daplatapus ID it. It does use up some calcium and grows fairly quickly. I will watch it and see what happens. It is kinda "pretty" on the rock, but if it grows too quickly, a hefty trim kills it apparently, or so says the ReefAquaria article.

Yes, I do know it is Aptasia. I have 3 or 4 of them and waitng for some Berghias to arrive, or I can use my "Magic" Aptasia wand to get rid of them..


I looked up Lobophora. It looks kind of similar, like you said, but nothing concrete to go by, from any of the pics I found online.

It is the other thing I am trying to ID. I do know the other is Aptasia.

Thanks for the responses, I appreciate them.
