Interestingly, stones in the aquarium serve not only a decorative function. Few people know that for many species of fish, a space arranged with stones is a spawning place that also promotes breeding. Some species also appreciate them as hiding spots from more aggressive fish. Regardless of the role that stones play in the aquatic life of fish, they are always elements of decoration that positively influence their sense of security and satisfaction. The same is true for the inhabitants of the terrarium, who love to hide in rocks that can also serve as a food bowl. Since the stones and rocks available at the Aquario.pl store are 100% natural specimens, it is difficult to accurately replicate the same model. Each stone is unique, which provides unlimited possibilities for changing the arrangements of the aquarium and terrarium. Underwater, it is worth paying attention to whether the stones and rocks will affect the water parameters. Some stones can change the pH and hardness of the water, which is why it is so important to ensure that we can use them in our tank when purchasing. To be sure that an aquarium with stones won't harm our water, it is advisable to consult experts from Aquario.pl.
