Yeah the second fish is definitely hard to tell but I think you should take a picture of it’s vent and post it to get a second opinion. Based on body shape and markings it looks like a male.
Update on my fader female! Also over the weekend I picked up a male for her cuz she was showing signs of spawning eggs put them in a 30 gallon together and they hit it off and became a pair instantly 2 days later she laid eggs male right behind her do his business
