MY pleco is gettin huge i have been feeding him blanched vegtables he is about 6 inches now and i have only had him for maybe 2 months, he is just a common and he is in a 55, and i know he will get to big but my lfs didn't have anything that stayed smaller so he told me that when he outgrows my tank i can take him back and get a smaller one (he wants to put it in his tank its about 12feet by 3 feet by 2 feet tall and has an arrowana in it)
