This weekend it'll be one week of clean, unmedicated water with both Fluval 303s running at 100% with carbon, too. If he still isn't eating and still doing the white poo, what then should I do? The poo doesn't hang. If that matters. I never see him pooping...and he's in a living room tank. There is nothing on the bottom and then there's some clear, whitish, yellowish, poo. Some where between mucous consistency and semi rubbery. Usually, it's somewhat stringy. The photo looks like there are tiny bubbles or dots attached. There are not. By the way, I've got a LOT of metro! Something tells me that I don't need it this time......I still have a supply of Metro., Kanamycin and the Prazipro...
