i was talking in a few threads about mantis shrimp and the sound they make and have now became paranoid....lol. there isnt any way a mantis shrimp could be in a system that hasnt had any unexplained deaths in over 2 years right? i know i had a pistol shrimp in there and thats probably the clicking sound i hear at night since its faster than the clicking the mantis makes at my work. any way just needed some reassurance here.
