My little fish has been swimming vertically for about 5 days. He is still eating but generally hanging out like this. There used to be a school of 4, but we seem to have lost one earlier this week (the tank cleaning crew makes it impossible to find the bodies... Great at their job )
Can high nitrates cause this? I'm currently sitting at 80 ppm and doing a 20% water change later today.
