I have some brown algae on the back of the tank.,tanks been running over a month and I have a Zebra Fish, Yellow Eyed Tank, 2 Clowns, Cleaner Shrimp and a Royal Gramma....I keep both sides and the front spotless but haven't done anything with the algae build up on the back painted black part. Is that ok to leave there? I don't have any algae anywhere else in the tank and my Yellow Eyed Tang seems to enjoy eating that
