Choosing The Right Ornaments
Ornaments add beauty and interest to large aquariums. Picking the right ones helps create a healthy and natural environment for fish.
Think about materials, safety, and size before buying decorations. These factors affect your tank’s look and fish well-being.

Choose ornaments made from safe and durable materials. Some common options are resin, ceramic, and natural stones.
