Went to pick up another glass for the top of my Aba tank and when I got back home after dinner, it was on the floor. Attempts at reviving it were futile. Really hurts my feelings. Sure did like it. The top was off for 2-3 hours and I even lowered the water level before I left home. It committed suicide after I came home with an Aimara Wolffish. Jealous I guess. Wouldn't have done anything different in hindsight. Aggravating.
