Ammonia boiling point and Water question

[Jimmyboi]

No idea if this forum is the right place to get the answer to this. But this is something I've been wondering for a little while. If ammonia has a boiling point of -33.3 degrees C, how can it be found in bodies of water such as lakes, ponds and even aquariums. A large portion of it is converted to ammonium which has a higher boiling point, but there is still the portion that is the more toxic ammonia that can be more harmful for aquatic life. How is this still present if the temperature is above -33.3 degrees?

The boiling points from oxygen, nitrogen and carbondioxide are more less as ammonia, but all can be dissolved in water. Othervise fish can not survive. So also ammonia has a good soloubility enhanced by hydrogen bridge bonds.
