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 appearance of brown algae in an aquarium is most often blamed on silicates in the tank water. Just like SPS corals that require calcium to grow, diatoms require silicates to grow. However, there are many other factors that cause brown algae and I believe the excess silicates story is way overplayed.
