How many fish can I put in my aqaurium? Verified

The following rule of thumb can be used: Per liter of water you can add one centimeter of freshwater fish or a half centimeter of saltwater fish. Keep in mind that this also depends on the capacity of the filter and the number of decorative elements in the aquarium.

I can't find anywhere how full the aquarium should be? In other words: how high do you fill it with water? Half way up the dotted top edge? Up to the edge? Or x number of cm below it? There are 2 grids on the left, one at the bottom and one at the top. The water level has dropped somewhat in recent days and now the water level is just below the top grid (so the pump can no longer drain there, I think.)
