The N. spendens very well could be, a few months back Wetspot did get in the real thing. I only mentioned it since I couldn't see the dual tail pattern on the male. That could be just because of the video though. If the top half of the tail is black and yellow horizontal stripped while the bottom is vertical blue and red, given the timing ... it would be the real deal. And also a huge score, one of the rarest Westies out there.
I would seriously doubt the G. geayi though. There used to be just one species, but they have been divided up into several recently and most places just use the old name. True G. geayi come from a country that does not have/allow commercial fishing. I could give a crack at ID'ing it if you can get a pic. There are subtle differences based on the black on the dorsal fin, the body stripe, and the mid lateral spotting. Most are usually G. stergiosi or G. sphenozona.
I would bet every dollar I have saved up for a new car that will have AC in it that the A. viejita are A. macmasteri. A. viejita just came into Europe and caused an explosion since, as far as I know, it's the first time it's been available in the hobby before.
