Saltwater Fish Diseases

There are a lot of saltwater fish diseases that your marine fish could suffer from.



Saltwater fish health can be taken care of by keeping the tank clean and making sure that the fish do not harass each other. To achieve this, fish must be paired with each other carefully. If you see any of your fish suffering from a saltwater fish disease, it is recommended that you should quarantine the fish and take appropriate measures for saltwater fish health care.

There are several types of Marine Ich diseases that fish can be susceptible to.



Saltwater fish diseases that affect the skin of the fish can be caused by parasites that grow in saltwater. An aquarium can be plagued by many such species of parasites. There is the white spot ich, the black spot ich, velvet fish disease, and another new strain of marine ich that can wipe out your entire tank within two days. When new livestock is added to a salt water aquarium, there is a danger of new parasites being introduced to the tank.



Since these parasites multiply and spread rapidly, they tend to be extremely contagious and may affect the entire livestock. Fish Ich can be diagnosed as an observable change in the color of the skin of the fish. If a fish appears to be covered in salt, it is a symptom of white spot ich. On the other hand, if you have a fish which has developed black colored spots on the skin, this is known as the black spot ich. Velvet fish disease is another saltwater fish disease that is caused by a parasite. However, this disease is not as evident as white and black spots. The parasite in velvet fish disease colonizes the gills of the fish, causing the skin to appear velvety.

Another saltwater ich is the clownfish disease. Though this disease is very commonly seen in clown fish, other fish are not completely immune to it. The clownfish disease is caused due to a protozoon which enters into the gills of the fish and begins to multiply rapidly. The skin of the fish can become discolored and a golden tinge can be observed. The protozoa multiply very rapidly and may even kill the fish completely in few hours of attack. There are many other bacterial viral and fungal diseases that can cause distress to your fish. The best way to deal with them is to change about 25% of the water in the tank every alternate day so that there is a proper nutrient balance in the tank. Also try and keep your tank as clean as possible so that there is no rotting organic matter in the tank.
