By using everyday items from nature, you can create a harmonious environment for your fish.

Choose colors that complement your theme or fish species to create a visually pleasing backdrop.

Arrange them tastefully among the substrate and decor to create a visually striking underwater landscape.

Ensure that the seashells and coral are thoroughly cleaned and do not leach any harmful substances into the water.

5. Smooth River Rocks

River rocks are not only visually appealing but also serve as excellent hiding spots for fish.

Their smooth surfaces and natural colors can enhance the overall aesthetic of your fish tank and provide an enriched environment for your aquatic pets.
