Aquarium decor refers to various items and materials used to enhance the appearance and environment of an aquarium. This can include natural elements like rocks, driftwood, and plants, as well as artificial decorations such as castles, caves, and colorful ornaments. Proper decor not only beautifies the tank but also provides hiding spots and enrichment for fish and other aquatic life. Choosing the right aquarium decor is essential for maintaining a healthy habitat. It should be safe for aquatic creatures, non-toxic, and suitable for the specific type of fish being kept. Additionally, decor can help create a more natural environment, mimicking the fish's native habitat, which can reduce stress and promote well-being.
