I'm starting to get algae in my tank(mostly brown) and am trying to find something to help get rid of it. I tried a scraper but the one I got is curved apparently and I don't like that it makes the algae float all around the tank. So now I'm wondering whether I should get a moss ball or something of the sort, or a snail or otocinclus. anyone have any opinions? It's a 13 gallon(wide and tall) with 5 neons, a betta and an amano shrimp.
