Spending thousands of dollars on a tiny bandit may not be a good idea. Although they do adapt quickly to captivity, bandits this small are very delicate and require constant attention to survive long term. For most hobbyists, it's better to go with one in the 3 to 5" range. If they've been properly handled and decompressed, they can handle the stress of shipping, holding, and acclimation much better than the babies.
I'd feel pretty guilty asking that much for a fish like this. It's normal for the juveniles to be worth more since they are hard to spot, but spending 5 times as much for a fish that's more difficult to keep is a little extreme. It's a free country, though.
