I went camping at Mohican state park and I checked on my fish before I left. My fire fish was eating and doing really well. I had friends/neighbors that were looking after my fish. The only other fish that I have in there is a lawnmower blenny. I know I have read about the fire fish being skittish to new people. I have not seen him since I got home. I have had my fire fish for about a month now and doing well so I have no clue what happened. Thanks. Oh. And I also checked my overflow and did not see him. I have a bio cube 29 with a lid
