How to Pick Decorations for a Fish Tank

When you start decorating an aquarium, you first need to decide what style you want to create, and then start selecting decorations. You should decide whether you want a purely natural theme or if you want something fantastical and fun. If you want to come up with a natural theme for your aquarium, then green plants, driftwood and gravel are ideal options. Think about the color of your fish. If you want something fantastical, you can create a decoration in the form of a dragon cave or buy some unique space decorations.

How big is your tank – 10 gallons, 20 gallons or 50 gallons? It is also important to determine the size of the aquarium so that it does not look like an overflowing storeroom but is also not empty. Arrange your aquarium so that there is enough space for your living creatures to move, play, and swim. When choosing decorations, pay attention to their height, so that they are very tall.

Decide what colors you need in the aquarium. You can add to or ruin the entire appearance of the aquarium if you select the wrong color. If you decide to create a marine-style aquarium, you can build a colorful reef. If the color of your decor and fish do not match, then the aquarium may not look very beautiful.

Choose the decor that suits your inhabitants. Some fish species need shelter, so you can create a grove of plants or install a vase in which they can hide. Overactive fish tend to have significantly higher oxygen uptake compared to inactive fish; for such fish, it is advisable to purchase oxygen-producing decorations, such as bridges, underwater chests and bubble chests.

Watch for sharp edges. Decorations, such as artificial plants, sometimes have sharp edges. Fish can get hurt on such decorations. When choosing decorations for your aquarium, make sure that they are safe.

FAQs

🐠 What types of Aquarium decor are there?

There are many varieties of aquarium decorations, such as plastic plants and ceramic caves. Some of the most popular options are artificial plastic plants, caves, rocks or synthetic corals. There are also organic decorations, such as driftwood, shells and dead coral.

You need to choose décor depending on the type of water that you use in the aquarium. If you have a seawater tank, you need to use special decorations, such as those made of synthetic rubber.

🐟 How to decorate the Fish Tank?

You can decorate your aquarium as you wish. If you choose a minimalistic style, you can choose from one to two small plastic plants in which your fish can swim.

There are so many different decorations that you can use. Depending on the type of water, you can even use live decorations, such as coral, plants and algae. Just make sure you know what type of water your aquarium uses to find suitable decorations. [4]

🐡 How to clean Aquarium decorations?

No matter what decorations you use, you will have to clean them. In order to clean the ornaments, you will need brushes, preferably with soft bristles, so as not to scratch the material.

To start, carefully clean the scenery from the accumulation of algae and other accumulated particles. After the seaweed and other dirt accumulations are completely cleared, wash the decorations under running water.
