The Boxing Glove Shrimp (not kosher)

Cool!!!

This just remided me of a story from when I used to have a salt water fishtank and I bought something called “live rock” for it (it is basicly just rocks taken straight out of the caribbean without being cleaned at all its supposed to be good for the tank) turns out there were some sort of baby shrimps living in it. Within a couple of weeks evrey night they would snap their claws really loud and make this loud cracking sound with their claws it was kinda unnerving at first because i thought maybe the glass was breaking or somthing, so i asked the pet shop and they said it does it with its claws themselves so i guess it was a diffrent type then this boxing shrimp… anyway after a while they just died i think, cuz they stopped making the sound, but i never really saw them anyway because they would hide all the time and i would only hear them at night.
