i have a tiger pistol shrimp in my 12gal and i want to put him in my 30gal. does anyone know how to catch him? i rarely see it cause its at the back of the tank. i really want a watchman goby for it. if possible please please please post a pic of a trap and how to make it. cause im not very good at making traps. oh and the pistol is kinda large. around 2ins big. sometimes it wakes me up in the middle of the night cause of how loud the clicking is -___-.
