Keeping an aquarium is a deceptively taxing responsibility. It needs care and attention on a daily basis. If you take care of general hygiene and the health of each and every fish, you can enjoy it for a long period of time. Looking for sick fish is an important aspect of aquarium care. A single fish suffering from some sort of infectious disease can spoil the health of all other fish present in the tank. Therefore, it is very important to find, quarantine, and treat the infected fish as early as possible.

Common Aquarium Fish Diseases

Bacterial Diseases: There are innumerable bacteria that can affect aquarium fish. Mycobacterium causes tuberculosis. The affected fish may lose color and get hollow-bellied. It may develop ulcers on the underside of its skin, which may rupture causing open sores or 'pop-eye'. Another bacterium called Aeromonas causes dropsy. The diseased fish shows some characteristic signs of dropsy. It has protruding scales, pale gills, bulging eyes, and its body cavity is inflated by fluid. It may have red patches on its skin. The bacterium Pseudomonas causes 'fin rot' disease. The affected fish has discolored fins. If it is not treated in time, its fins may start to disintegrate, and it becomes more prone to fungal infections.

Fungal Diseases: Many kinds of fungal infections are life-threatening to aquarium fish. Fungi such as Saprolegnia and Achlya cause a disease called 'cotton wool disease'. As the name suggests, wool-like masses can be seen on the fish's body. Another fungal disease, gill rot, is caused by Branchiomyces. The affected fish has gills covered with mucus. The gills also appear mottled in appearance. This particular fungal disease occurs in concentrated aquariums with high levels of ammonia or nitrate. A common fungal infection of aquarium fish is ichthyophthirius multifiliis, or ick. It is caused by a protozoan, Ichthyopthirius. Fish suffering from this disease develop small, round, ulcerated, black granulomas on the skin. They often show scoliosis. On internal examination, numerous granulomas can be seen in several visceral organs.

Viral Diseases: Lymphocystis is a common viral disease in both marine and freshwater fish. The commonly affected fish are cichlids and gourami. Lymphocystis is not infectious. It mostly develops in response to poor environmental conditions and stress. Poor aquarium conditions, especially water quality, is usually held responsible for initiating Lymphocystis. The affected fish develop wart-like growths on their fins. These growths are often colored light brown, and have a rough, cauliflower-like texture. Another common viral disease is caused by the dwarf gourami iridovirus (DGIV). The diseased fish show discoloration of the skin, loss of appetite, and reluctance to move. They may develop sores and lesions on the body.

Non-infectious Diseases: These are caused by environmental, nutritional, and genetic factors. Some of the environmental factors are high amounts of ammonia, high levels of nitrite, low level of oxygen, or toxins in the aquarium. The main nutritional factor leading to such diseases is a deficiency of vitamins. The setup of the tank, or the makeup of the diet will have to be changed to remedy these conditions. Genetic abnormalities can't be controlled, and are, by definition, a random aberration.

Now, you know the characteristic symptoms of some commonly occurring diseases. Make use of the given information to the fullest to let your pet underwater world flourish.

No one really likes to talk about worms, but they are a fact of life for most horses. They good news is that you can treat them quickly and easily. You and your horse will both feel a lot better. The downside, though, is that the worms aren't as dumb as we think they are. They find great ways to avoid what people use to try to control them, and they can make your horse sick. They cause diarrhea and weight loss and colic, and if they aren't treated a horse can eventually die from them. Even though most horse owners try hard to control them, vets regularly see horses that have worms, and it's becoming a real problem. Different worms cause different kinds of problems, and a low level of infection isn't going to be a big deal. It's almost impossible to keep a horse one hundred percent worm-free all the time. It is the high levels of infection that people have to worry about and that must be gotten under control.

When treating your horse for worms, being educated about horses and their problems can help you do much better in taking care of any difficulties that arise. Not all horses are the same, and individuals who are aware of this can do better in caring for their horses. Some horses are more likely to get worms than others, and owners who know this can treat their horses more aggressively. Some worms also have to be treated with different kinds of medications than others, so treating for one kind of worm won't get rid of all kinds of worms. In addition, some medications are only good for one lifecycle, so the worms might return. Owners who are aware of these kinds of things and prepared for them have much happier horses.
