Help me out, guys. What's the best way to deal with the brown algae that is growing over my gravel and decor? I understand that there are some critters highly adept at eat algae, but I'm not sure if my tank can accommodate another creature. Need an expert opinion.
Tank details: 5 gallon, heated, filtered, cycled. 20% weekly water change.
Tankmates: one betta, 4 ghost shrimp and several live plants.
