Ok ... Three times this week I've discovered something new in my tank. First was a brittle star, second was a really cool sponge and now this popped up outa no where....
I have those on a rock in my tank. They have the look of a anemone but they have a calcium structure in the rock. They don't spread fast at all. I had like 2 the rock they are on have no much xenia they can't be seen at all.
and one of my favorite corals of all time. I had a bluish purple one that hitchhiked on a gorgonian and it was gorgeous. Feed it like any other LPS. Enjoy.
