Hi,
I have had a tank with a few zebra Danios and the filter had broken so I had a new one today and it has a spray bar instead of just pumping oxygen into the tank. I have noticed my danios have been going to the surface. Is this normal?? I have also seen some yellowing in the bottom of a few of them
