Gender identification of juvenile RIvulatus GT's isn't easy. It's been my experience that even juvenile male GT'S have bright Irridecent scales with thicker, more vivid orange or red fin edging. Males often have more defined spangling behind the eyes & down the cheek.
Female coloration isn't nearly as vibrant. Of course their are exceptions. Here is a pic of a baby GT male I'm currently growing out. He was just under two inches at that time.
I'm guessing your GT is female.
