DIY Aquarium Decorations

How To Decorate An Aquarium

What you need to create DIY aquarium decorations:

  • priming;
  • driftwood;
  • vegetation;
  • pebbles;
  • seashells;
  • glass figurines;
  • ceramic items;
  • plastic parts;
  • background.

When choosing a decor, give preference to natural materials. They are the safest for living inhabitants. Plastic can be harmful to fish as it produces toxins. If you decide to decorate an aquarium with plastic, buy it in specialized stores. You can give up living creatures and fill the tank with fake fish.

Aquarium soil

Carefully consider the choice of soil. The whole composition depends on the quality of the primer. The size of the soil depends on the choice of fish. For small live fish, sand is suitable. For larger fish, use rocks. Gravel, volcanic rock, granite, basalt, gneiss become a ground cover. When choosing a soil, keep in mind that some rocks lead to an excess of calcium in the water. This is undesirable for fish, as the water will become hard. The color of the soil can be of any color.

Do not allow soil with limestone to enter. Before using the primer, check it for lime content: drip vinegar onto the surface. If there is a hiss, the soil is not suitable.


Driftwood recreates a natural underwater environment. They really look original, you cannot find a repetitive snag. Small fish like to hide in snags. Choose branchy driftwood that will provide shelter for several fauna. Natural wood increases the softness of the water.

You can buy ready-made driftwood at the store or find interesting wood yourself. Please note that you cannot lower pieces of wood that have not been under water for a long time.

Do not decorate your tank with a few large driftwood. They look bulky and take up a lot of space. One branchy driftwood is enough to create a natural ambiance of the underwater kingdom.

The choice of plants depends on the type of reservoir. Saltwater aquariums require specific environments and plants, while freshwater aquariums require different requirements. The choice of vegetation is influenced only by your imagination: they can take root at the bottom, attach to the walls or float freely on the surface. Think in advance what you want to get from the vegetation. Javanese moss looks beautiful. They can be used to decorate figurines, driftwood, caves, pebbles to recreate the effect of the underwater world.

The advantage of moss is that it does not require any maintenance, it grows quickly, neatly framing the decor.


You can find all kinds of beautiful pebbles in pet stores. There are large, colored, smooth, pointed rocks. When choosing stones, be careful: some rocks can only be kept in fresh water, and some only in sea water. Sea pebbles can upset the acid-base balance in fresh water, which can be bad for your fish. You cannot take street stones and immediately throw them into the water. They need to be thoroughly rinsed, checked for compatibility with vinegar, and only then immersed in water.

Incompatible rocks:

  • marble;
  • a piece of chalk;
  • limestone.

Neutral breeds:

  • quartz;
  • basalt;
  • granite;
  • slate.

You can use pebbles or seashells in fresh water. Before placing them in the aquarium water, treat the stones with boiling water.


The background decides a lot in a decorative aquarium. There will be no problems with the background. Pet stores sell beautiful decorative films that are attached to the back wall of the tank. The film can be attached to double-sided tape or with a glue gun. The background color depends on the overall decoration. If you want to recreate the effect of depth, buy a dark background. For a bright aquarium, buy a backdrop with light landscapes. The themes of decorative films are so diverse that everyone will find a background to their liking.

Decorating an aquarium is fun. You will spend several evenings decorating, but it will bring you incomparable pleasure. Not a single dry aquarium in the interior, made by hand, is not repeated. Use your imagination, embody interesting ideas, find unusual decorations for the aquarium. But remember, the aquarium is where the fish live, so leave room for them to move around. The decor should be not only beautiful, but also safe for all inhabitants of the underwater kingdom.
