Definitely looks like a guy to me! So pretty!
I had the same problem with "Tifa" about a month ago. I bought her as a female, and "she" was incredibly aggressive. No egg spot, and I found a bubble nest in "her" tank. Turns out it's a male! After nursing him back to health from that hell we call Wal Mart, his colors brightened and you can definitely tell he's a male HMPK. :)
