This is a program in german language, which helps you to get an overall view about the stocking density of your aquarium.
You could choose the contents of your aquarium and set how much decoration the aquarium should hold.
Now the program calculates a minimum length und a minimum volume.
This gives you an appropriate standard aquarium.
Alternatively you could choose your own aquarium in a list, and then you could stock it with fish, until the calculator notifies that it is full.
Please note: This is the first version of the program. The social behaviour of the fish and the required water parameters are not considered.
This program is freeware and is provided by www.bachflohkrebse.de, a mail order firm offering fish food.
