After observing this fish some more, I think it might be a female. It was sold to me as a male, however, the black on the ventral fins, throat and the lack of a dark spot on the caudal peduncle makes me think it's not a male.
I can take additional pics to upload if that would help anyone.
Look for a specimen with a slightly serrated dorsal fin - particularly toward the front - a blue body cast and a more horizontal caudal spot that extends into the tail fin.
