I never move my fish!
Fish can die when they are moved as this stresses them.
When you clean them even refrain from moving them,
empty half the tank with a jug or cup and then fill the rest of the tank with treated tank water.
the densities are different (Saltwater has a greater density than freshwater.)
It can realy vary depending on the location of the freshwater climate.
Freshwater snails typically grow to be around 1 to 2 inches in size.
It is usually around 9.25 pounds.
Around 68.7% of Earth's freshwater is currently inaccessible, as it is stored in glaciers and ice caps. This inaccessible freshwater is primarily located in Antarctica and Greenland.
because it goes in circles like going around the world
about 3% is freshwater
it changes depending on where it is
For freshwater, I would say around 7.
Most of the freshwater on Earth is found in glaciers and ice caps (around 68.7%), followed by groundwater (around 30.1%), with a very small percentage in rivers, lakes, and the atmosphere.
By volume, that would be Lake Baikal located in southern Siberia, Russia. It holds around 20% of the world's freshwater.
Freshwater has a lower concentration of minerals and salts, around 1%, while saltwater is higher in dissolved salts giving it a higher concentration, around 3.5%
