Haemaglobin levels should return to normal within 12-24 hours. If severe anaemia is present, recovery may take weeks. The original cause of the nitrite toxicity should be resolved. Levels of nitrite in the water can be reduced through water changes, biological filtration and decreased feeding.

Different species of fish tolerate different levels of nitrite. Some fish may simply be listless, while others may die suddenly with no obvious signs of illness. Common symptoms include gasping at the surface of the water, hanging near water outlets, rapid gill movement, and a change in gill color from tan to dark brown.

Can goldfish get nitrate poisoning?

Even though your goldfish may tolerate high nitrate levels in its main tank or pond it may be injured after a large water change. Goldfish suffering nitrate poisoning must have deep water. The pressure created from water relieves the pressure caused by nitrates.

But sometimes, it can be really difficult to determine when your goldfish is sick. They’re hardy fish that can brush off symptoms that would kill lesser fish.
