why are cherries being so still
i went to look at my cherry tank to find them being very still in their tank. some were moving about but for the most part, a majority of them were just kind of standing there. about an hour or to prior, most of them were swimming around and stuff. i checked the water and everything seems normal nitrite are 0 and ammonia is 0. could it just be that they're asleep? do they even sleep?
