60 gallon tank, 4ft wide, 20 inch tall. I've had Ottos before, I wasn't overly impressed with them. I had a huge pleco who did well but his poo out paced his cleaning usually. I thought Amano shrimp might be bigger than the Rams could eat. Or the Cherry shrimp might out breed the ones eaten. A YouTuber recommends Hillstream loaches as well. Just looking for something different I guess. I know my algae will melt away soon enough, my tank is typically very clean and has a CO2 bottle, high lighting and ferts. It is balanced and consistent, I just got lazy for a month or so and algae went crazy on me.
