I don't think you'll know what species he is.
If he's tank-bred, he's probably mostly H. efasciatus/H. appendiculatus. I had one that was the same color. He was a great fish and a great parent, but also pretty rough on my other tankmates. I still had a real soft spot for him.
Unfortunately the flash made him look more of a deep green color, but under tank lights he was a pretty steely blue.
