get it back to the LFS is just like run away from his responsibility, most of people I see buying a 10'' RTC after it being brought back to the LFS don't even have a 100 gallon tank!
for the OP, if you have enough space indoor and money to buy a stock tank, there is a website that sell 610 G stock tank for less than $300 ($270 if I'm remember correctly) with free shipping that you can get a stock tank from!
I hear what you are saying. But considering it is in a 10 gallon, if he isn't able to get that stock tank quick, I don't see the fish living for very much longer. Thirteen inches of RTC is a whole lot of fish for a 10 gallon.
I always cringe anytime I see RTCs, Pimas, Tiger shovel Nose (name any cat that gets huge) in a fish store. The people that have the knowledge and resources to properly care for them probably know how to special order them. I know it's just business, but I think it's irresponsible for shops to sell these monsters to any kid that has $40.
