Wayne, I disagree. I don't for a minute believe the lion did that, I'd be looking for a hidden crab. Another possibility is the tail got stuck between some rocks and broke off during the struggle to get free. Try looking for the tail piece...

Since these fish aren't huge swimmers, the space should be fine as long as water quality is maintained.
