(commonly known as freshwater white spot disease, freshwater ich, or freshwater ick) is a common of . It is caused by the . Ich is one of the most common and persistent diseases in fish. The protozoan is an . White nodules that look like white grains of salt or sugar of up to 1 mm appear on the body, fins and gills. Each white spot is an parasite. It is easily introduced into a fish pond or home aquarium by new fish or equipment which has been moved from one fish-holding unit to another. When the organism gets into a large fish culture facility, it is difficult to control due to its fast reproductive cycle and its unique life stages. If not controlled, there is a 100% mortality rate of fish. With careful treatment, the disease can be controlled but the cost is high in terms of lost fish, labor, and cost of chemicals.
Most common diseases among aquarium fish are:

When fish are injured, for example by fighting or fin-nipping, their skin is broken and bacteria will enter the wound. Ordinarily the fish’s immune system will destroy any invading bacteria, preventing disease, but if the fish’s immune system is weakened through stress, poor diet, or most commonly of all, poor environmental conditions, the invading bacteria are able to establish themselves inside the wound. Therefore whenever mouth fungus appears, the aquarist should check the fish aren’t fighting or nipping each other, that all the fish are being maintained in appropriate social groups, that their diet is balanced and vitamin-rich, and that water quality is satisfactory. Non-zero levels of ammonia and nitrite are particularly strongly associated with mouth fungus, though water chemistry and oxygen concentration issues may also be at issue.

Let's face it. How many of us haven't had to deal with an aquarium fish disease of some sort? This is a serious issue and many times aquarium fish disease can be avoided or prevented altogether by going slowly, following proper acclimation, quarantine and dipping procedures.
An article providing information on UV Sterilizers and their use in the aquarium. The UV Sterilizer might help reduce fish disease outbreaks, but they require a slower flow rate to kill parasites. These sterilizers are not as good as using a quarantine tank, but may be a nice addition to your tank since they can also help control algae growth.One of the problems that many fish keepers face is the daunting task of identifying problems in the aquarium. Unfortunately, lack of experience, or subtle signs of stress can let a disease run rampant until it destroys the infected fish (sometimes the whole aquarium). I have included this page simply as a guide for diagnosing diseases in Tropical Fish. It is by no means complete, and I cannot guarantee that it is 100% accurate, but should help steer you in the right direction.n early the 1970's, when I was just 13 or so, ("marine ich") and ("marine velvet") were a bit less of a problem for my fish than they are now when I quarantine new fish as an aquarium curator. The reason was a product called Marex from the Aquatronics Corporation (they have long ceased operations). Marex was sort of a wonder drug for us back then - simply adding a single $1.99 dose protected the fish in a 50 gallon aquarium from many diseases plus it killed the unsightly algae that grew all over the tank decorations back in those days! When the company went out of business I moved on to using other products. For the past 25 years, I've been using ionic copper measured with a spectrophotometer twice a day to control marine ich and other protozoan diseases. Copper is slow to affect a cure, and the difference between a therapeutic dose and a dose harmful to some fish species is slight. Still, it seemed to be the best method for quarantining or treating active diseases in fish. Thinking back to when I was a youngster, I did some research and discovered that the active ingredient in Marex was chloroquine, and I was familiar with that drug as it was being used by other public aquariums. Acquiring some myself five years ago, I've begun incorporating it into my arsenal of aquarium fish disease treatments. A few home aquarists have begun re-exploring its uses as well, often calling it by the shorthand name of "CP" which stands for chloroquine phosphate. This article provides those aquarists with additional background information to enable them to be better able to use this "new" drug if they wish - having options is always a good.
