Hard to tell from those pics but I'd say both male. Females have white edging on the top and bottom portion of the caudal fin.
This is a female

Did they just eat before you took that picture?
Females of pretty much all species of pikes will generally have a "beer belly", which is noticeably more robust than the males. Most species, but not all, will also have at least some sort of pinkish hue to cherry red on the abdomen as well.
Another thing is the top pike has striations on the belly/body, while the bottom pike doesn't. A somewhat fairly reliable way to sex is by the striations, males will have it on belly, females won't. Its not 100% though.
At this point its looking like male top, female bottom, but they look really young in those pictures. Give them a few months to develop and be patient. Maybe you lucked out and got a pair, but only time will tell.

Not aggressive at all by Crenicichla standards. My pair lived in a 125 gallon tank along with large silver dollars, small Hoplarchus and a group of large bosemani. The worst aggression was the male pike on the female.

Man those are some nice pikes.
