This thing came on my liverock. When I first put the rocks into the aquarium, it crawled into a hole in the rock. I assumed it died in there, but here we are 3 weeks later and it reappeared out of nowhere.
I'm thinking more along the lines with Kip. Do a search on here. They can be kept, but I believe it's still a type of nuisance anemone. Keep an eye on it.
