Litres for a domestic aquarium, kilolitres for a large [public] aquarium.
Humidity is a measure of the amount of water in the air, compared to the maximum possible amount that could be dissolved.
No, a hygrometer measures humidity; the amount of water in the air.
salinity
Realative humidity
you dont count you measure it

I am guessing you can use Gallons.
For the volume you can use a graduated container.
Measure its dimensions in inches or centimeters, and its volume or capacity in gallons or litres.
If you are trying to measure concentration of salt in water you would be measuring molarity which is moles / liter. Moles are equal to grams of salt / the MW of salt (and if you mean NaCl then the MW is 58.44 g/mol). Density is a ratio of mass to volume (mass / volume or kg/m^3)
The instrument that is needed to measure the temperature of the water is called an "Aquarium Thermometer".
the amount of water
Because the fish need the enough amount of water every day of their lives
gallons
