Did you buy him from sharkaquarium or rich (infinite aquatics)? hehe I bought some from both. And, from what I can tell in your pic? It look's like it could very well be a armatus. I would need to see a clear pic of the adipsoe fin or you would have to update us when you grow it out a bit? If, it's only 2" then you won't be able to see any orange. At,3" you will be able to clearly see the orange with black lining on the fin.
i have small armatus too
