It almost looks like a hybrid between a banded and millennium. It has the stripes of a millennium, but isn't as colorful. However, in that pic it looks like it has a band. I don't have the fish next to me right now, but I'll try to upload a video of it soon.

Mainly identifiable by the single red orange spot on the gill plate or cheek directly behind the eye, also two rows of light tourquoise striped scales directly above the lateral line of the fish.
Are there any oddball's around here that may be able to give us a second or third oppinion, please? But I am quite certain I am correct.
