Fish are only one type of animal that eats algae. There are many algae-eating snails, shrimp and clams that can be interesting additions to your tank. Florida flagfish (Jordanella floridae) are great additions to the aquarium that has a brush or beard algae problem.
The majority of algae eaters will also only consume certain types of algae, most will not eat fiberous stringy algae or black/brown fur-like brush algae and very few if any will eat the velvety blue-green algae which forms a 'carpet' over plant leaves and substrates.
