I just wanted to share my experiences purchasing 2nd instars. I've only bought one sling at that size, and it died one day after arrival. Ive purchased several scorplings at that size, all recently, and I've lost 4 out of maybe 15 of them, to unknown causes. I had seen a few veteran breeders suggest to people that they shouldn't buy them that small, and I'm finding out rather quickly that they were right. Of course when theres lots of babies in a brood, or sac, some just aren't meant to make it, but most of the sickly ones will perish before 3i, and scorps and tarantulas both seem to become a little tougher once they reach that mark, and less prone to die suddenly for unknown reasons. Just a little advice: 3i is the magic number. Don't waste your money. Breeders know all this, but some will sell them to you anyway. Beware people trying to unload 2i babies as fast as they can.
