I know what you mean about worrying that you'll get what you see. I've never actually ordered livestock from an online vendor, and that is the main reason why. that and the fear of death upon arrival. Although most companies now offer livestock arrival guarantee, I'm still a little wary.
Where did you hear about them by the way? I've never heard anything about em either.
My friend Jeremy and I found them purely by chance one night two years ago, and we've been hooked ever since. We've only so far been able to drool over the corals...never had a decent chance to order any.
