Hi, I have a healthy 3-inch Humma Humma in a seventy-gallon tank along with a clown, falco hawkfish, and a one fox face rabbit fish. I have an algae problem, mainly film algae and algae in my substrate. I was wondering if there are any inverts I can add to help this problem that wonââ"šÂ¬Ã¢"žÂ¢t be dinner. Or any fish for that matter. I am doing two ten-gallon water changes a month and two five-gallon water changes a month and it is still not under control. Any help would be much appreciated. Thanks
