I think it's a ZZ, there is no distinct coloration, but very nice scales.
Also, it might be too young to sex, but I'm still a noobie at sexing so maybe someone with more experience at sexing would be able to tell better than I could.
I was hoping some one would say this. I thought it was a female myself because the lack of color, and sort of narrow body shape towards the tail, although, that could just be because it's still young. I am hoping it's a female because I bought a much smaller male red dragon. He's probably around an inch and his fins are all red, and some red on his chest. He's in the same tank but it's divided so he doesn't get killed by the bigger FH, I also have a small Texas Cichlid with the baby FH
