that fish is a Male, females dont have the dots/spots all around the body, when my Dovii's were small the one i thought was the Male was actually the female, she was eating like crazy and out growing the male by two to one, i was thinking it had to be a male, nope. she had no spots on her and the male was way to small for me to tell at the time, when the male started growing he started looking a lot different from the other one, then i was on a site that explained the difference between the two, low and behold the big one i thought was the male actually was not, she had no spots at all, and as the smaller one began to grow his spots got more and more pronounced when you see them both now its absolutely plain as day who the male and female are.
