I have heard many differing opinoins about what to feed plecos. I have a couple of friends who have never feed thier pleco, and it is now over 10 inches long and has been alive for a number of years. THere are also people who feed thier plecos all the time. What is the best? Also, i tried to feed my pleco algea wafers, but the goldfish will just pluck at it untill it nothing but a floating cloud? What to do?
