Many years ago i had a 55 gallon FO tank. at one point my inhabitants included a lion fish and a lemon peel, among a couple other fish. one day while standing in front of the tank the lion fish swam up behind the lemon peel, and, well, you know the suction power of lion fish...... well the lemon peel was too big for the lion fish and after a few seconds he spit the lemon peel out. it was pretty surreal. the lemon peel lived for a few days and then died. I am now exceptionally knowledgeable about fish compatibility!!!!! live and learn.
