On my way out the door to work one morning I found my LMB totally crispy, not moving and covered in cat hair and lint on the tile - popped him back in the tank and by the time I got home he was good as new.....freakish.
My yellow wrasse also jumped out twice - once I found him right away....the second time, not so lucky
I miss that fish!
I think some fish can last longer than others.
