stuff that will creep a person out. so there i am watching the coral beauty swim around the tank. doing what coral beauty's do, what ever that is. and i see an eel head sticking out from a rock. the rock the beauty is swimming through. then i see an inch of eel. then 3. the beauty is frozen in its tracks so to speak. then the eel kinda "hugs" it, then the beauty swims on and the eel slowly retracts into its hole in the rock.
freaked me out thought i was watching the end of the coral beauty and the impending flushing of an eel.
