Fish gills are red in colour why

1.	Fish gills are red in colour why
Answer» High levels of ammonia can buildup in your\xa0fish\xa0tank. This often occurs when a tank is newly set up or when too many new\xa0fish\xa0are added at the same time. Symptoms include\xa0red\xa0or purple\xa0gills\xa0and/or\xa0fish\xa0gasping for breath at the water surface. The ammonia level can be reduced by a neutralizer and by a 50% water change.\xa0The\xa0gills\xa0lie behind and to the side of the mouth cavity and consist of fleshy filaments supported by the\xa0gill\xa0arches and filled with blood vessels, which give\xa0gills\xa0a bright\xa0red colour.
