I have an established 90 with a lot of rockwork. I have tried, unsuccessfully, to add a diamond watachman goby (twice), and a yellow watchman goby. All three went through QT, but disappeared after the first night in the display. I think the culprit is a pistol shrimp that I can hear, but have never seen. So, my question is, how do I catch a shrimp that I never see?
