It's just a sales technique really, call the fish something else and people will get curious and buy it thinking it's extremly rare, or uncommon. Most of the time the fish is something common, like a pearl in think case. It's like calling neons cardinals, they look quite similar when they're small, and cost buyers a couple of dollars...Often you'll see that they're mislabeled because they don't know any better...sylvia said:
I agree with everyone else that they are probably pearls, but they could also be young snakeskins. I'm really thinking they are mislabeled pearls. There is no snakeskin pattern on them, just the pearlescent (and soooo very shy!). Each and every one in the tank was a female except for 1 male, and he had the orangy male coloring.
