Maybe a type of majano? The stalk looks thick for an aiptasia. Neither are good... but personally I'd rather deal with majanos.

But... a little off center and down a bit... that might be an aiptasia...

Don't panic, it's manageable and just part of the process.


Erik, good guess on the spaghetti worm! That matches the description pretty well. I hate those things. They're gross. Harmless, but gross.
