Fish usually eat everything in my tank I put in it, and also I have a pleco that seems to keep most of it off glass and such, but it seems to like growing and showing on my friGgin white sand
And it weird cuz when I first set up the tank I never got any brown algea on anything... Just all of a sudden it popped up after being setup for awhile ??...... Not sure what brought it on.. And even my 75g I have had for a lot longer NEVER gets or has brown algea in it but it has just a stand 4ft florescent bulb agua glo I believe it is
