thanks guys. I had 100 of pets and a mantis shrimp is by far the smartest animal I ever had. They will also look you right in the eye and if you move your head they will move with you. I will post a video of him smashing someones lights out have to many of them lol. When they smell potential food they will fight to the death for a simple meal. You def don't want one sneaking into your pretty peaceful reef tank because as soon as the lights go out its killing season!
