Just some friendly advice about SAE's. If you get SAE make absolutely sure you get true Siamese algae eaters because you would not want false and definitely not those horrible Chinese algae eaters. Chinese algae eaters get big and they are MEAN and contrary to their name, they don't eat algae. Many, many many many many many many MANY places falsely label flying foxes/false algae eaters as Siamese and most only carry those terrible Chinese algae eaters. Look up Google how to tell the difference between flying foxes and SAE because they look similar.
SAE will eat Black beard algae which I have no doubt you'll get, bristle nose pleco prefer to eat bio-film on surfaces and fish food personally I view them to be terrible "algae eaters" I imagine if they were never fed they'd eat it but they prefer fish food and Vegetable over algae.
