Ichthyophthirius (white spot)
Ichthyophthirius is the name of the parasitical organism responsible for this disease,which is easily recognised by a rash of white spot covering the body and fins.The spots are about the size of a pin head,and are caused by the parasite burrowing just below the skin and setting up an irritation.The first sign you may get of white spot is that your fish dart about among the plants or flick themselves against the rocks to ease the irritation,and the barometer of health,the fins,will be laid flat,not erect as with healthy fish.
If white spot is not cheacked at this stage,the spots multiply rapidly until they cover the whole body and fins in a film of fungus, which soon results in death.
The main cause of the trouble is a chill brought on by a sudden change in temperature.This change need not necessarily be of a low temperature,a suuden drop from 26celsius to 23celsius is quite sufficient.Yet another cause is the introduction into your tank of a new specimen which has the disease.
The first step in the cure is to raise the temperature to 30celsius and to keep it there for several days.
Another method is to use 2drops of 5percent aqueous solution of methylene blue per gallon of water in conjunction with a temperature of 30 celsius,but this stains the sand and is notgood for plants.
