I can testify for the quality of Vivid Aqaurium's livestock. I have had many orders from them and all but one arrived healthy and in good shape (a tang with ich died and they replaced it). Any BTA sold from any vendor may not take on the same color in the purchaser's tank as it was seen in the seller's pic. Color, like expansion and bubble tips, are dependent on lighting and a host of water parameters. That nem looks healthy and robust to me- its final color will depend on who buys it.
