Why can't you put pebbles in the fish tank?

The reason why the fish tank can't put pebbles is because there are gaps between pebbles, so that when feeding at ordinary times, the bait that can't be eaten will fall in, leading to water pollution.

If you really want to put it, you usually only need to lay one layer, and the thickness is not more than 3-4 cm. In addition, clean it regularly, remove pebbles when changing water, and then discharge the dirty things inside.

In the aquarium landscaping, it is a relatively precious stone.

Some aquariums also choose coral as decoration in order to simulate the landscape of the underwater world. There are many kinds and shapes of corals.
