Can anyone help me identify this? He showed up (with a friend) in my tank after I upgraded my lighting. I am pretty new to reefing and still learning my Anemones (not to mention corals).
Many thanks in advance

That is an aiptasia anemone and it is usually considered to be a nuisance hitchhiker. They are best removed or killed Do this a quickly as you reasonably can as they can easily over run a tank.
