Heaters are generally reliable, but when they go wrong the consequences are usually devastating. Both ammonia and nitrite affect gills and can cause gasping, so test the water at the first sign of trouble. When ammonia is present fish produce extra mucus, which reduces the surface area of the gills, making them less effective at extracting oxygen.

How can you tell if a fish has an infection?

Look for signs of infection such as spots, clamped fins, secondary infections such as fungus or bacterial diseases. Many of these attack gill tissue, which either damages those tissues or causes the fish to produce extra mucus that could reduce the amount of oxygen fish can extract.

What happens when ammonia is added to fish?
