coconut straw

Can be used in an aquarium as a natural substrate or as a decoration. It can be used to create caves, hiding places or resting areas for fish. It is important to note that coconut straw can release tannins into the water, which can change the color of the water and lower the pH. It is therefore advisable to soak the coconut straw for several days before using it to allow these tannins to escape.

It is important to regularly monitor the water parameters to ensure that they remain within the appropriate limits for the fish you have in your aquarium.
