Aquarium Fish Health: The White Spot Disease And Its Treatment

One of the most frustrating moments in the life of a fish breeder or fish owner is when one or more fish dies. And this is one of the most common problems aquarists face. But sometimes, no matter what you do, death is inevitable especially in a fish tank. Many diseases are caused by internal or external parasites that live in the tank.

This is why you should observe as often as possible your fish and detect the problem in early stages. Many diseases, if discovered quickly, can be treated.

White Spot disease is one of the most common infections that appear on fish and is caused by the parasite - Ichthyophthirius Multifillis which swims and attaches itself to the fish.

Here are some behavioral symptoms in a fish that is infected with White Spot disease. If you notice some of them, start a treatment.

- The fish looses its appetite and has no response to food

- It stays constantly on the water surface or on the ground
- If it stays on the water surface it opens the mouth frequently and gasps for air

- The fish has a tendency to get close to the rocks and rubbing the body to against them

- Lethargy and a general state of weakness

- Hovering in a corner

- While swimming, the fish keeps the clamps up.

But one of the most obvious signs of infection is the pin head-size white spots that appear on the fins and sometimes on the whole body. This is a clear sign of infection with White Spot Disease.

This ailment can be treated with a solution of Methylene Blue. This solution can be bought from a chemist or from any fish shop. The treatment is like this: a 1% stock solution is poured into 0.8 to 1.0ml per gallon of tank water. Ad all the amount at once and repeat the process in a day or two. Before you start the treatment it is good to remove the dirt from the bottom of the tank and use aeration with bubbles near the water surface. A dirty tank bottom could inactivate the solution by absorbing it.

It is very important not to interrupt the treatment till all the white spots are gone. After the spots disappear, change all the tank water because a long exposure to the Methylene Blue chemical can affect the fish’s fertility. If used in a weak dosage, the Methylene Blue has no side effects to young fish and also to aquarium plants.

If your filtration system is charcoal based, you should consider removing it, so that the Methylene Blue isn’t absorbed by the charcoal.
