OK i just by chance out of the corner of my eye saw the craziest thing in my tank.... holy crap!!!! i don't forsure know what it is but i am hoping that if i describe it someone might know. I'll start off nice and slow......phew...take a deep breath......I saw a turbo snail flopping back and forth like they usually do when trying to get something off their back but this one was being grabbed or more like engulfed by a fluid creature, and by fluid i mean a squishy soft thing like maybe a squid or octopus or cuttle fish. so anyways the snail is a gonner its whole body and shell was covered by this tan colored stretchy mass that leaked out of a hole in a rock under my LTA and slowly retreated back into the hole and left a bare shell. no tenticles just a large blob that was tan in color and had some cross thatch pattern all over. it could stretch and move I am Officially freaked right out!! I need ideas and suggestions as i know this is not reef safe....things have been disappearing .
