Now a days armatus are pretty much the same price of a tat. But if it's size you are worried about then take the tat back as armatus of course grow bigger and faster.
Ya that definitely screams tat. The armatus and tat can have identical looking adipose fins but the difference is that a that's will match the color of its tail whereas an armatus won't.
@ characinator i checkt withe the guy that sold it to me and he showed me that the invoice label sad it came from Colombia.
Dont know if that helps at all.
Why are you having so much trouble accepting that its a tat, not armatus? Even though it's collected in Columbia, it doesn't change the fact that its a tat. Armatus and tats are both found thoughout South America so that doesn't really change anything.
