I also recieved mine, and have nothing but rave reviews.
They are definitely armatus, and they came in perfect and healthy. The larger one is already starting to do the snapping jaws/yawn customary to both of my big armatus, and the smaller one is about to shed a tusk, and I can see a replacement flipping up into position already.
I also am having a bit of trouble trying to find small enough guppy babies, but I have some extremely small minnows in there now, and both of the armatus made a pass at some of them, but backed off. I'm not worried; they'll eat them.
DB Junkie has been posting a lot of "comparisons"/trash but the fish I bought from aquascape definitely look more like armatus than the others I have seen. Well worth what I paid for them.
Thanks Aquascape/Pedro.
