Male or female rainbow cichlids

[Hybridfish7]

This one is from a fish that is aggressive and has a slim body. I can't tell with head shape because it's sort of inbetween.
Same goes for this one but this one is slightly bigger more mellow, and taller bodied.

Top one looks to be possibly male while the bottom one I would say is a female based off of vent size compaired to anus size.

spot on, they just spawned, so that verifies things
