well i found my large jag beat up today. i thought the butti might have snapped and did it but after watching the tank for a hour i realized it was the female festae. i cant believe it they have been in the tank for along time and were alway paired up. i guess this recent mating activity made her mad. id never thought my 9 or 10 inch festae would have beat up my 14 inch jag. jag is ok and will recover fine. i moved him to a seperate tank until he recovers. i almost think he didnt fight back because he liked her and let her do it. weird
