For a 60-liter fish tank, you'll generally need about 1 to 2 inches of gravel for proper substrate depth. This translates to approximately 10 to 20 kilograms (22 to 44 pounds) of gravel, depending on the type and size of the gravel you choose. It's important to consider the specific needs of the fish and plants in your tank when determining the exact amount. Always rinse the gravel thoroughly before adding it to the tank to remove dust and debris.
For a fish tank, you need enough gravel to make a thin layer on the bottom of the aquarium. For an outdoor walkway, you need much more.

No, a two liter bottle is too small to support fish. Fish need a certain amount of water volume, oxygen, and space to swim and thrive. It is not a suitable environment for fish to live in such a confined space.
