I've had my YWG and Pistol shrimp together for about 3 months or more. But for some reason I haven't heard the Pistol shrimp popping sound it usually makes and I see the YWG come out and eat. This is the first time the shrimp has ever went silent. Where the Goby goes the shrimp is always on its hip. Been almost 2 days and not a single pop or peep from the shrimp. I'm praying its not dead because removing rockscape to fetch it would be a nightmare. Is this normal behavior for this shrimp or you think it's dead?
