L046 sexing?

[Hf21]

Hi, would anyone be able to sex the photos attached of l046? They are all diff fish around 3 years old. I’m not great at sexing them so any help would be appreciated!

It would be easy for me to search online, but what is the sexual dimorphism that would indicate male or female?

No, I don't keep Zebra plecos. I kick myself for not getting them back in the 1990s when I think that they were about $25 retail.
