What can kill a fish?
by
Fish may die of old age, starvation, body injury, stress, suffocation, water pollution, diseases, parasites, predation, toxic algae, severe weather, and other reasons. A few dead fish floating on the surface of a pond or lake is not necessarily cause for alarm.
Uneaten fish food releases toxic ammonia and nitrite as it decomposes. This is especially dangerous to newer aquariums where the nitrifying bacteria that gets rid of these toxins hasn’t had a chance to fully develop. High ammonia and/or nitrite levels can stress and even kill your fish.
Does salt kill fish?
You do NOT HAVE to add salt to your freshwater fish system.
Aquarium or pond salt is the safest choice for fish systems. And make sure it is SODIUM chloride “salt.” POTASSIUM chloride is toxic to fish and will kill them. Do not use marine or coral salts in freshwater fish systems.
However, overfeeding fish can be a serious problem that can cause fish becoming lethargic and sick, and even lead to death. Overfeeding your fish can not only affect the health of your fish but can also have a negative impact on the overall health of your aquarium.
