This table is by no means complete nor may it be 100% correct but it will give you an idea of which species of algae-eating animal you may want for your aquarium or pond.
Both the likelihood of eating algae and eating plants applies to adult specimens and not to juveniles. Some species propensity to eat algae varies with age such as with most of the algae- eating fish. The species that are most available at the aquarium or pet store are those that the salesperson is most likely to try to sell to you. They also often cost a lot less than the other, less- available species. Do not let a salesperson sell you an animal that is not appropriate for your particular situation. For example, do not put a common plecostomus in a tank under 40 gallons unless you plan to give it a larger home later, or do not put one of the smaller species below in with larger animals that may eat it.
