So I have brown algae growing on my glass and it's a pain trying to clean them every week. I don't overfeed my platies and I have my lights on for about 8-9 hours. I'm thinking of getting an algae-eating fish to solve this problem. I'm wondering if I should get a nerite snail or an ottto. I have a 20g with 4 platies and will be getting 3 or 4 more high fin platies soon. If I get a snail or otto, what should I feed them after the algae are gone? Will they take algae wafers; specifically from these brands: API Algae Wafers, Tetra pleco wafers, and Hikari algae wafers. Are these good brands that contain the right algae substitute because I heard that you need some algae-related meal instead of fish meal.
