  1. Looks like black beard algae but I’m not sure, not harmful just annoying, feed the tank less it could be a surplus of nutrients &I see someone mentioned light u could reduce how many hours the light is on, don’t worry about it too much tho, a fish tank is an ecosystem and algae just happens to be a part of that

    I think its excess of phosphate and lack of nitrates or that’s what usually causes that kind of algae
