I have a 60 gallon with three goldfish in it. Over the past week my two fancies have started spending a considerable amount of time at the top just gulping air. My black moore does not gulp at the top and swims around normally. All fish are healthy and still eat normally. No fungus or disease is present. I recently did a 30% water change a week ago and I use a gravel vac about three times a week to help remove excess waste and prevent ammonia build up. I have a marine land 400 power filter made for up to 90 gallons and I also have a bubbling volcano to help add extra oxygen. I've heard heard their gulping behavior may be due to lack of oxygen in the water but if that was the case why would my black moore not be gulping for oxygen as well. Any suggestions about this problem?
