the first picure is 100% a male pk as netty said, the 2 "frilly" bits are called ventrails and males are longer then girls but not in the pk thats why so many are sold as females, he has a full beard to you can clearly see that in the picure so yes 100% male.
the second one i would say female, yes she has a pointed long dorsal fin but that means nothing when it comes to these fish, i had a lovely girl that was bought as a boy her fins were the same
We have took that look maleish, and this is the best i could get of the both, they seemed to be hanging out with each other the moment i was doing it which was good
The fuzzy pictures make it really hard. What we need to make a definite judgement is clear pictures of them flaring. But I'd say they both look like PK males. You don't get ventrals like that on females.
