Sorry for your loss. I too had lost a fish due to an unsafe hollow ornament. It had a larger opening on one side and a smaller one on the other. There wasn't enough room for the fish to turn around and exit, so he was caught in there. Ever since, I carefully inspect every ornament before purchase. My requirements are: if it is hollow, the inside must be completely empty, no passage ways, multiple escape holes and it must be smooth on the inside. Otherwise, I stick to rocks and driftwood.
