i think flowerhorn, def female imo. i hate it when people say low grade... i think she's really nice and many flowerhorns that are bought cheap are nice, just because someone invented a grading system dont mean anyone has the right to throw their opinions at other peoples fish esspecially when it will put a downer on a lot of peoples fish... unless you asked the grade of course. grading only counts in kamfas if i remember rightly, looks more golden monkey to me. also remember a flowerhorn is a hybrid of many or sometimes just a few fish if someones in the early stages of creating their own. most have trimac in them and a mix of amphilophus. in the early pics i thought i was seeing some festae in there. i have and have kept many aggressive cichlids together in communitys for years and am yet to have a fish go beserk and KILL EVERYTHING! all fish are different and i say if you like her try it out for a while and imo if problems arise you'll have some warning signs, just have a sturdy divider or spare tank at hand. good luck and keep us updated.
