Well, apparently something was meaner than he was cause I can't find him anywhere in the tank. Pretty sure he is a goner. He was out a bit after I put him in and eventualyl went to hide behind a rock. I watched and he was there til I went to bed. Checked this morning and he is nowhere to be found. I looked through all the rock and found nothing so I'm not sure if I'm going to get another and see what happens or leave it at that and add that to a list of no-no's for this tank. If anything, I think it could have been my goby. Mean sob, he just looks mean. Killed the pistol shrimp I tried to give him too.
