My family had a pleco that lived for about 8 years. When we got it at the pet store, we were told that it wouldn't grow much larger (it was under two inches). If I recall correctly, it ended up growing to be about 6-7 inches in a 30G-ish tank. Knowing this, I wouldn't buy another one unless I had a lot more space. They are kind of boring and poop a lot. They do, however, seem to live a long time...
