Parachromis Managuense sex?

[LDPatton]

I have 5 jags that I bought to grow out until I coukd sex them and pick the best male if there was one. I believe I correctly sexed the two biggest ones based on growth and the pattern of spots. Last night I removed the second largest and one of the two smallest ones to place them in a different tank.
heres a pic of the second largest Jag. From what I can find it appears to be male. What do the experts say?

No one has any input if this is a male or female based on the vent pic?

pops what do you think with the other photos and video? The jag is a little darker due to some squabbling and tension. Its time to sell the other jags and permanently home the male I keep so theres no aggression issues. This is why I was hoping the vent pic and other pics would get me some input from members who know more about venting and sexing by body type and pattern.
This jag and the largest jag setup territories and defended them against each other and the smaller jags. I have no doubt the largest jag is a male based just on growth and the fact hes very spotted with some purple sheen. I could be wrong tho but I am pretty confident in his id. If this jag is a male it would help confirm the sex of the largest jag without having to stress him by removing and venting.... at least I think it would.
