The fish looks male and I can see a male tube in the both pics.
male
100% male
I would say male I have two at 3.5 -,4 inch s my female is yellow and has solid bars with her mouth starting to fade to red . And Male is exact to yours has the two eye spots along top of his body and only displays his bars when he's stressed and even then they are very lite.
