The signs of health problems in fish tank

 

Accurate diagnosis of a disease over based solely on behavioral or physical changes of the animal is impossible. However, there are "clinical signs" that may be useful in identifying possible problems. Most of these symptoms are caused by several diseases and therefore thorough examination and medical tests are essential in formulating an accurate diagnosis. The following is a list of some symptoms and health problems that may indicate.

Many aquarium fish die in a short time without any signs of any disease. Fish that survive are floating on the surface or the bottom of the aquarium and lose their balance easily. Animals are lethargic and not eating. These symptoms could indicate acute poisoning. Water should be tested for various substances and fish examined for bacterial or parasitic infections. If possible, examine the newly dead fish. If tests are negative, change up to 75% of aquarium water. Send and water samples for toxicological tests.

Fish rub against solid objects will try to jump from the aquarium or will be apathetic in the current filter. This behavior indicates a form of irritation of the skin or gills. The problem may be caused by high levels of ammonia, nitrite and pH. Sudden changes in pH level of water can also cause skin irritation fish. You need to check all water parameters. Irritation may occur as a result of this ectoparasites, such as trichodina and Tetrahymena.

 

 

Fish swim normally but appear to breathe hard and pant. These symptoms may indicate hypoxia, triggered by low oxygen levels in the water too. Measure the oxygen tank and filters especially in the morning, when it has the lowest value. Low water quality can cause gill hyperplasia, excess mucus production or nitrite levels excessively. Check levels of ammonia, nitrite and pH. Also, make sure that the tank and filters are clean. The same clinical signs may indicate anemia, if gills are pale.

Necrotic tissue loss usually affects the top fins, but there are cases where you can see a hole in the middle of one of the fins. The appearance of such disorders range from a wound like a bite up to an area that seems torn. Almost all cases of loss of rotted tissue are caused by stress, fear or poor conditions in the aquarium. You should try to find the stress, it can be infected with a parasite, the low level of oxygen in the water tank or over-population. If you quickly identify and remove sources of stress fish may recover without needing medical treatment.

A fish with digestive system problems will occasionally float to the surface water and will swim for a long time leaning to one side. Discourage the fish to swim to the surface when I feed. Who fail to grasp food fish near the surface and very much likely to swallow air. Also, food will be more dry than when it reaches the bottom of the aquarium. Thus, pieces of food will swell from moisture in the digestive tract of fish and produce kidney blockage.
