High levels of ammonia can buildup in your fish tank. This often occurs when a tank is newly set up or when too many new fish are added at the same time. Symptoms include red or purple gills and/or fish gasping for breath at the water surface. The ammonia level can be reduced by a neutralizer and by a 50% water change.

Swimming Disorders If fish are swimming slowly or with clamped fins, gasping at the surface, listless, not eating, or if their gills are purplish rather than bright pink-red they are not getting enough oxygen. Check your water's pH, nitrates and ammonia levels. Do a few water changes and check your filters.

While it is possible for a fish to survive in a bowl of water, consideration should be given to the quality of that fish's life. ... Like other animals, fish breathe oxygen and release carbon dioxide, using their gills to extract oxygen from the water.

The symptoms of ammonia or nitrite poisoning are often lethargy, red or inflamed gills (gill covers sticking out when the Betta is resting and not flaring) and gasping for air. ... It can be difficult to treat the gills once they have been burned by these toxins but there are steps you can take to help your Betta out.

Saltwater fish produce very little urine in order to hold onto the now more pure water created through this elimination of excess salt. A freshwater fish, on the other hand, does hold onto the salt in its body because there isn't as much of it in its environment.

Answer: The correct answer is feather. If lungs are called gills and gills are in turn called feathers, then fishes breathe through feathers. Gills are respiratory organs found in aquatic organisms like fishes, using which they derive oxygen from the waters and release carbon dioxide.

Gills are evaginations of the body surface. Some open directly to the environment; others, as in fishes, are enclosed in a cavity. In contrast, lungs represent invaginations of the body surface. Many invertebrates use gills as a major means of gas exchange; a few, such as the pulmonate land snail, use lungs.

In the case of freshwater fish, their blood and bodily fluids are much saltier than the water they swim in, so water will flow in through their gills. ... As well as getting water through osmosis, saltwater fish need to purposefully drink water in order to get enough into their systems.

The major means of respiration in teleosts, as in most other fish, is the transfer of gases over the surface of the gills as water is drawn in through the mouth and pumped out through the gills. ... Several genera of teleosts have independently developed air-breathing capabilities, and some have become amphibious.

Fish use gills to “breathe” the dissolved O2 in water, and human lungs do not have enough surface area to absorb enough oxygen from that dissolved in water, that's why human lungs are designed to breathe air and the lining of the lung is optimized for breathing oxygen from air not oxygen dissolved in water.

The main difference between gills and lungs is that gills are the type of respiratory organs specialized to breathe in water, whereas lungs are the type of respiratory organs specialized to breathe in the air. Furthermore, fish use gills while mostly tetrapods use lungs.
