Okay..i knew about the power of the pistol shrimp but i totally didn’t realize that they would use it on cleaner shrimps. I used to have a mantis shrimp that killed off alot of my cleaner shrimps until i finally caught him. I know that i also have a pistol shrimp somewhere but after i caught the mantis shrimp, i still lost any new cleaner shrimps. So I thought maybe i still had another mantis shrimp (or an evil crab..more on that guy later) But after watching this video…i think i might know who the culprit is!
