My pygmy cories in my 6-gallon seem to be going up to the surface for some air more than my pandas do in my 29-gallon. I'll see them do it maybe twice an hour. Is this okay? I have a filter that moves the water around and I have live plants, so I don't think oxygen is a problem. When they dart to the surface real quick to get some air, does it mean I have an oxygen issue?
