I put a diamond goby in about 6 weeks after I got the pair and he dug them out of their home twice, they split up and i saved the watchman, he was being chased all over the tank by my diamond, I have not seen my pistol shrimp. I put the watchman in my frag tank and got him another pistol shrimp. My diamond goby (Diamond Jim) is very large and I think that was part of the problem. If I could do it over I would have let the pistol and YWG goby grow to adult size and then put a very small diamond goby in. You live and learn! Bud, I believe you've see Diamond Jim.
