My Nitrates are extremely high. I had 5 gallons of water and did a exchange. The tank is 65 gallons. Everything looks ok but my big clownfish is swimming at the top. He has been doing that all night . I have had him for 3 years. The nitrate with the API is 80 ppm. As soon as store open I will change water. I transitioned my animals to a new tank or at least the store owner did. My nitrates have never been that high. Is there a quick fix? Is that why my clown fish is swimming at the top? The little bitty clown fish is acting normal.

have you found out what is causing the nitrate spike? Not sure about the bigger clown though. Most of the time fish is more resistant to nitrate than the corals in my opinion.

Lack of oxygen. Promote the best gas exchange with pumps up directed to water surface.
You have not dosed carbon, have you?
