Anyone knows what this is and more importantly should it be removed?
Found it hiding in the dark and is about an inch across.

The rock was bought from a local hobbies that was closing down his tank. The fact that it's probably been here for some time and I have not lost any fish and there still is only one make me less worried. I have also convinced myself it's not a majano, so I will wait and keep an eye on it.
 
hehe i meant indo or what not but if it was in a local guys tank it doesnt matter as it may have moved there...

it loks far to small to eeat any fish, yet....and i am pretty sure it is not a majano....looks like one of them atlantic ones though...

not sure
 
It may be a ball anemone (can't remember the scientific name for anything tonight). They're actually more closely related to mushrooms than anemones. They don't need or even appreciate a lot of light. I don't think they're bad, although I guess if they spread they could cause problems. I've had them in several of my tanks with no ill effect that I've been able to discern.
 
It is a carribean Corallimorph. According to the book marine inverts, its on page 118. It says they lack zooanthenallhae but do well in heavily fed tanks. Will reproduce faster if fed small pieces of fish. Its a mushroom.
 
On closer look I completely agree with plateboy3293 and rssjsb, The ends of the tentacles are ball shaped. This is larger and is not as transparent as the usual "ball anemone" but it does not like the light and seems to be growing ever since I have increased the feedings.

I may have to pick up the book 'Marine Inverts'.
 
Can I ask where you're located? I live on the gulf coast, and I'm always checking out the local marine life, and that looks exactly like an anemone that I've seen. I don't know what it's called, but if something bothers it, it turns into a little brown ball.

I kept one for a while with my first try at a salt water aquarium, and it was very hardy. It was also very aggressive. It caused chemical burns on anything that came close to it, and successfully killed both fish and shrimp.

Although I later returned it to where I found it, I was pretty impressed by it, as well. I usually keep local cleaner shrimp in my tanks because I like the way they look and their cost (free) and because they're from local waters...but I couldn't keep them with this anemone. They were eaten too fast. So I started buying live gulf shrimp to feed them. My little one (started out about a 3/4 inch button) could eat an entire 6" shrimp in under 30 min. It was amazing to watch.

I released it about 6 months later when it was I caught it trying to devour a 4" Sargent Major, (another local fish).

Anyways, if anyone's interested, I've got a few pics somewhere, and I can try to get a pic of them in the wild. :)
