For a dwarf, yes they are slightly more aggressive than others of the genus. By declawing them, you're stripping them of the ability to breed and acquire food. I would rather toss them into boiling water before that.
They are no thread to tetras or smaller fish. I've kept them with Endler's livebearers before and the fry of those are smaller than any tetra that you'll probably keep.
Lastly, consider the cost of C. patzcuarensis var. 'orange' versus the price of a tetra. Unless you're keeping some exotic tetras, the price differential is rather large (e.g. neons vs. orange cray - ratio is 25:1 if the neons are $1 each).
