You can but it is not healthy fro your fish and increases the chance of disease and can shorten there life span. It can also make your water cloudy very rapidly which is also likely to kill your fish if kept in over time. A good rule is 1-2 inches of fish per gallon or 1 cm of fish per liter. Be sure to keep in mind that the fish will grow.

Can you keep 5 goldfish and 2 zebra danios in a 21 liter tank with decorations?
This is not a good idea. 7 small fish - for example 7 zebra danios - would fit in a 21 litre tank provided it had strong filtration, and frequent large water changes were carried out (50% weekly.) However, goldfish are absolutely not suitable for this tank. For starters, goldfish grow extremely large - the 12 inch long monsters you see in people's ponds are exactly the same species as the small fish sold for aquariums. If given adequate food and space, they will reach this size. It is extremely cruel to keep them in a tank that is too small to allow them to grow. Also, goldfish are extremely messy - they require more food and produce more waste than most fish. With such a small tank, you're better off sticking with smaller, nano-friendly fish. Zebra danios are a good choice - they are attractive, stay small and will forgive a beginner's mistakes. You could also consider small tetras or livebearers. Don't try to keep more than six or seven small fish, or you will overstock the tank.
