Also that fish may have been died for awhile so that's why my parameters may have been all over.
Yep, that would probably elevate it. Good idea to remove it promptly. I should practice what I preach. I have had 2-3 fish die off in my 20g long tank over the last year. Never found the bodies probably because the tank is over grown with plants. Maybe the Amano shrimp feasted on them...idk.
