Aquarium caves and hides A fish with nowhere to hide lives stressed, gets sick more often and barely shows itself. A few caves of the right size and material completely change how your tank behaves. See comparison → 
Aquarium backgrounds A background hides cords and the wall, adds depth and makes your fish's colors pop. It's one of the cheapest upgrades you can make, but it's best decided before the tank is filled. See comparison → 
Aquarium gravel and sand Substrate isn't just about looks: it affects bottom dwellers, plants and even water chemistry. Getting the grain size, color and material right avoids problems that are a pain to fix later. See comparison → 
Aquarium rocks Rocks give your aquascape structure and your fish cover, but some change the water chemistry. Knowing which stone is inert and which is calcareous is the difference between a stable tank and one with runaway pH. See comparison →
