Choosing the Right Size and Shape

When selecting volcanic stone, I considered the size and shape that would best fit my aquarium. Larger pieces can serve as focal points, while smaller stones can be used to create a natural look. I also kept in mind the swimming habits of my fish. I wanted to ensure that the stones wouldn’t obstruct their movement or create hazards.

Most fish do well with this type of substrate, but I ensured that the stones didn’t have sharp edges that could harm my fish. I also focused on the needs of my specific fish species, as some prefer more hiding spots than others.

In my journey of setting up a fish tank, volcanic stone has become a fantastic addition.
