Is Black Beard Algae Harmful To Plants?īlack Beard algae often first appear on your plants. Once that happens, properly maintaining the tank will become more difficult and levels of toxic chemicals might rise, too. Also, an overgrowth of algae can cause an imbalance in the levels of nutrients in the water, which could potentially make the environment unsafe for your fish. That said, a blanket of black algae clinging to every single surface throughout your tank is very unsightly. In fact, some small fish species seem to enjoy playing or hiding among the flowing manes of algae, and shrimp keep busy picking out fragments of food that have become caught in the beard. In short, no, colonies of Black Beard algae growing in your fish tank are not going to harm your fish or invertebrates. It’s really just a matter of personal taste. For example, a dense, flowing forest of dark green Black Beard algae growing over a piece of twisted root can create an interesting feature. However, if you control the spread of the algae and limit its growth to certain parts of the tank, you can incorporate the organism into your aquascaping. The main problem with the algae is that they can take over your tank, coating objects within the aquarium and covering the viewing panes.

Black Beard algae are sometimes also called Brush algae and have the scientific name, Audouinella.
