This hamlet appears to be a cross between a Yellowbelly Hamlet and a Yellowtail Hamlet. These are pictures of the actual fish in stock. It is 2", and eating everything. It is a purplish/blue/black hue (depending on light and fishes mood) with a yellow tail, anal, caudal and ventral fins. The dorsal is almost entirely yellow as well. This is a stunning and truly one of a kind hamlet!
