we need some more info to be able to help you, how big is the tank, litres/gallons and/or dimensions (lenth, width and height)

what equipment is running on it, filter heater etc?

exactly what fish do you have in it, how many of each?

what is your maintenance routine?

do you add anything to the tank?

describe in full the symptoms, when it first started, had anything been added to the tank around that time? how often are fish dying, how long are they ill for etc

have you tested the water, post your stats for ph, ammonia, nitrite and nitrate.

that should give us enough to start with.
