My 5 Danios, Platys and swordtail. along with other fish constantly hang sroun dthe top of the tank. i cant see them becuase of the cover and i can bearly see the rest of the tank, they havnt always done this, and also i only got the danios yesterday. I do have a small amount of ammonia and nitrite. but my tanks about 2 months old now, and nearly cycled i believe. any reason why they might be at the top? and any way i can help it? there are plenty of hiding places so i have no idea. I heard they may be ill/distressed. Help please
Thanks, Zak.
