Ammonia, if allowed to accumulate, is toxic and is converted to less toxic compounds or excreted. … Ammonia is eliminated from the blood upon passage through the gills.
Do all fish excrete ammonia?

Is ammonium toxic to fish?
Ammonia exists in water as either the ammonium ion (NH4+) or the un-ionized ammonia (NH3). Un-ionized ammonia is toxic to fish, while the ammonium ion is nontoxic except at extremely high concentrations.
Is ammonia toxic to humans?
Ammonia is corrosive. The severity of health effects depends on the route of exposure, the dose and the duration of exposure. Exposure to high concentrations of ammonia in air causes immediate burning of the eyes, nose, throat and respiratory tract and can result in blindness, lung damage or death.
What is ammonia in fish tank?
Ammonia (NH3) is the most toxic nitrogenous waste found in the aquarium and is capable of quickly killing fish, or causing them to become diseased. It’s produced in the breakdown of organic materials, and by the fish themselves as a by-product of their metabolism.
