Some plecos are herbivores (algae, vegetable matter), some are omnivores,(eat a little bit of everything)and some are carnivores.(meaty foods)
Many of the plecos will eat algae when small, but soon lose interest when they discover that scraps of fish food are much easier to find than rasping on wood,glass,decor, for a little algae. Bristlenose Pleco
is a fairly good algae eater that stay's relatively small at around five inches and eats' algae whenever,and wherever it can find it.
The common plecos seen most often in fish store tank's grow very large,produce ton's of poo,.and are generally poor algae eater's except when juveniles.
The Chinese alage eater, is another often seen fish in stores and oddly enough ,isn't from China,is poor algae eater except when very small, and can often terrorize other fishes in the tank as it matures.
Smaller alage eaters that don't create much in way of extra bio-load are Otocinclus,shrimps,snails but these may become snacks for larger fish, so care must be taken when choosing what alage eater's are placed in what tank ,with what fishes.
