I had a male FM who was a complete MORON. He was very "aggressive", flaring and charging at all fishes in my tank. One day, he thought he became super strong and faced my male red devil, twice his size. Well... They lip-locked, and the RD took his lips off. His mouth was simply ripped off his face. RIP, stupid FM. Not equipped to serious fight... Too much barking and little biting.
