My 8" Oscar jumped tank on Thursday - slipped out of a 2" gap in the glass lid that I had failed to get recut after breaking it a few months back. Didn't find him until Friday morning shrivelled up on the living room floor. It was one of those "what's that" moments when I saw the lump sitting there. Didn't even clue in until I was right overtop of him.
Lesson learned - glass was recut and placed over tank by Sunday
