You won't find them online. Most places don't bother to ship them. They're large, heavy, and fragile all of which means specialty shipping. Most places won't bother to even offer it because not many people are willing to pay $50+ to ship a $12 dollar tank.

I don't really know what to tell you, I can find anything from a 2.5 gallon tank up to a 200 gallon reef ready where I live. Petsmart, PetCo, Pet Supermarket, and both my LFS are lousy with the things.

If you're having trouble with a ten I'd actually recommend looking for a 20. The cost difference between the two isn't that much, maybe $20 dollars and it'll be more stable and give you more options.
