Well people feed their plecos an "array" of foods so they grow very quickly, but feeding 1 time a food causes the grow quick but not as quick. For example, I have two plecos, that I got at the same time and same size. If I had them in seperate tanks and fed one only sinking pellets or wafers and he only grows 2" in the first year. The other one I feed wafers, zuccini, greens and whatever else, and he grows 4" in the year. The one that had more variety grw larger.
