What type of pleco do they sell at Petco? My brother has had one for several years and it has only grown to about 4-5 inches. I thought it was a clown pleco until we saw some large ones (probably about 12 inches) at Petco a few days ago. I assume they are the same species? Does the tank size inhibit their growth?

probably a Common or Sailfin pleco (two different types). They are the most commonly sold plecos on the market.

Yes, tank size does inhibit their growth, more commonly known as "stunting". If kept in an undersized tank, a fish with the potential to attain about 2 feet long will only remain as much as its surroundings allow it. However, only the outer part of the fish stops growing, the internal organs continue to grow, making this a painful experience for the fish. If your brother has a common pleco or a sailfin pleco, and has had it for several years, chances are, its had its growth stunted. Plecos can grow very quickly. I had a common pleco and purchased him at around 3 inches long. No later than 3 months go by and he's grown to about 6 or 7 inches long. I eventually had to rehome him.
