I am kinda new to the pleco world. I have had my sailfin pleco since he was about 2". I feed my 8" sailfin pleco a steady diet of 1-2 algae pellet a day, and about 2-3 leaves of romaine lettuce/ or a slice of apple a day. My pleco does not look skinny, but I am afraid I might be underfeeding. If he was your pleco, how much more would you feed him? Because they are "grazers" it is kinda hard for me to decide how much.
