Fish decorations are an essential part of any pet aquarium. Gravel and sand provide a natural look and feel to the tank, while decorations such as artificial plants, rocks and driftwood can make the aquarium look more attractive and interesting. Gravel and sand also help to keep the water clean and provide a substrate for beneficial bacteria. Decorations can also provide hiding places for fish, helping to reduce stress and make them feel more secure. With a wide range of fish decorations available, there's something to suit every aquarium.
