i had a 13inch female manganuse/jag for alittle over a year, it was mean as hell!
it had permnant pms issues! i kept chaseing my pirahnas around and it kept trying to eat them! (they were 5-6inches)
it was in my tank with my RTC and my Rtc didn't like it hovering over it so i got rid of it 1 1/2 months after i stuck it in my 11inch electric catfish tank because, that female jag was really not scared of any fish accept my RTC.
It came out all it's scales where burned but it clam down only for a month!(nuts....)
(I wanted to teach it fear so it won't be so agressive...)
