It is not tank size but water quality that stunts fish growth in a larger newer tank there will be less Nitrogenous waste in the tank giving a simingly faster growth but after a point in time that growth will be inhibited by waste. Now If anyone has the time/money/space to preform a TRUE Test on this IE you'll need a Control and keep all other uncontrolled variables at a minimum. I'll be interested to see the truth.
IME the only reason my fish have had a growth spurt from moving to a larger tank is because the tank has been BRAND NEW leaving a possibility that it was the age of the tank and not the size.
Lastly, I'll be willing to bet that the 10gal set-up had higher Nitrates/older than your 29gal
