Various types of decorations are placed in aquariums: both natural (such as roots, stones, or plants) and artificial (such as castles or caves). However, it is worth remembering that not all of these decorations are suitable for each type of fish. For example, stones change the hardness of water, and placing roots in an aquarium can lead to the development of algae. Most jewelry can change the pH of the water. In addition, it should be remembered that sea turtles present completely different requirements than fish regarding the arrangement of aquarium decor.

You should be careful when buying artificial elements. Not every castle that looks beautiful can be safely placed in an aquarium. First of all, you should never place any artificial figures (for example, toys) in the aquarium that are not intended for this purpose. This can cause fish poisoning.
