Brand new and more than a little confused.

Was just watching the tank (nose pressed against it lol) looking for signs of life when i noticed a little pink anenome thingy lol. about a cm tall and i can see through it, bulb shaped.. fat on the bottom thinner on top with tentacles waving around. first sign of life in my tank... any idea what it might be? I'll try to take a picture but my camera isnt that great.
