How Many Fish Can I Fit In An Average Fish Tank?

Depending on the size of the fish, you can fit anywhere between 10 to 20 fishes.

A general rule of thumb is to have 1 cm of fish for every 1 litre of water in the tank. If you have 100 litres of water you can have 10 fish of length 10cm, 20 fish of 5cm etc.

Make sure that water is clean.Do not over-feed the fish, when changing water always not more then 20% of the volume of the tank do not over feed.
