Types of substrate for freshwater aquarium – Why is it used

Why do pet owners take a lot of effort and time while choosing a substrate? It is because they are helpful not only for the pets staying inside the aquarium but for the plants as well. These are some of the most important uses of an aquarium substrate.

  2. They also help some of the fishes to thrive well inside the aquarium and also helps to keep their eggs safe from the eyes of the adult fishes. For example, when marbles are used, the eggs fall between the stones and are hardly noticeable.

What to note while choosing the right types of substrate for freshwater aquarium

  • Choose the size of the substrate after doing considerable research about the type of fish that you own. Some fishes love to eat the fine substrate particles along with their food, whereas some varieties of fish fall sick when particles such as sand or gravel get inside their stomachs.
  • Choose colors that will aggravate the beauty of your fish pets. For example, if you have a light-colored fish, choose a dark-shaded substrate so that the contrast looks perfect and beautiful
