What Can I Use for Creative Christmas Fish Tank Decoration Ideas? – Best Unique Ideas

What can I use as fish tank decorations? When deciding on the creative Christmas fish tank decoration ideas you want you’ll add to your aquarium, you need to take into consideration the advantages and drawbacks that each could bring.

1. Driftwood

Natural driftwood is an extremely popular accessory to aquariums of all kinds and is a great way to give a natural, simple feeling. It can also be an ideal hiding place for shy fish.

Driftwood can be purchased in a wide range of shops and is typically secure. It is possible to take driftwood from streams and rivers, then add them to the tank with no amount of money.

Be cautious in this regard and be certain to keep wood from wild sources in a quarantine. If you do not, you run the risk of adding dangerous parasites and microbes that have the potential of making your fish very sick.

Boiling driftwood prior to placing it into an aquarium will help to remove some tannins from the wood. Tannins are safe for fish, however many dislike the fact that they make the water appear brown

2. Aquarium Stones and Rocks

There are a variety of attractive stones such as pebbles, stones, and pebbles that are available for sale, which make an excellent addition to aquariums. They are also great for tanks that are themed to nature and can soothe the fish in the same environment as their natural habitat.

You could also include rocks from nature in the aquarium. Prior to doing this, it is essential to cleanse the rocks prior to adding them in order to prevent the introduction of harmful organisms.

Be aware that some rocks, including lacy rock, could be sharp and cause injury to your fish, and should be avoided.

Additionally, certain rocks contain calcium, which can be absorbed in the waters, which can harden it in time. However, this is not necessarily a negative situation, especially if have very soft water.

It is possible to test the rock samples for calcium content using an aquarium liquid testing kit for nitrate. Tests for nitrates are made up of two bottles, which are usually identified as bottle 1 and bottle 2. Bottle 1 is filled with hydrochloric acid. If you apply just a few drops of the acid on a stone, and it begins to form a foam this means that this rock has calciferous. This will release minerals into your water over the course of time.

Never boil or bake rocks. The rock could cause it to shatter, or even explode. The most effective method to clean rocks is to use the bleach method that I discussed in”the “Sanitizing Non-Commercial Items” section above.

3. Caves

The addition of caves in a tank can be a great method to create hiding places for fish. Sometimes, fish can feel intimidated or scared and need some space to hide.

Some species, such as catfish and plecos are full-time, cave-dwelling fish. They’re night-time creatures, spending their time in caves and only coming out to eat after it gets dark.

Therefore, adding additional caves could help diversify your fish. Each fish establish a home turf that helps them feel safer.

7. Bubble Makers

Bubble chests, rivers under the water, and air stones do not just look beautiful but are usually a necessary element in aquariums that are crowded.

If you’re keeping a few actively active fish in one tank, you must make sure they are getting enough oxygen.

Fish that are busier will require more effort than species that are slower Therefore, it’s essential that you keep the oxygen levels up by adding decorations that produce air.

Incorporating bubble makers into your aquarium, make sure they’re not too heavy for your fish. If the water flow is excessively high, your fish will struggle to swim and will become stressed which can result in illness.

The flow of water can be reduced by adding large objects such as driftwood.

10. Ceramic Ornaments

The incorporation of ceramic ornaments into an aquarium is a controversial practice, with some hobbyists proclaiming they are completely safe, while others are completely against their use.

In reality, some ceramics are, in fact absolutely safe, while other ceramics release toxic metals when their glazes break down and may be extremely harmful to fish.

Anything that is marked as “dinnerware safe” is suitable for use.

It means that the glaze was fired using techniques that avoid chemical leaching in acidic conditions. The non-dinnerware items are not in compliance with these requirements and are not recommended for use.

If you’re uncertain regarding the safety of a ceramic ornament dilute acid from your home like vinegar until it reaches levels that are similar to most acidic conditions your aquarium might be in. The pH should be 5 or higher. is recommended to suffice.

Infuse the decoration, or a portion of it, into this solution and then wait for a month to examine it once more. Verify the glaze. If the shine of the object has diminished it is a sign of chemical leaching and that the object isn’t suitable for use in water.

Plain, unglazed ceramics such as terracotta are appropriate since they have no danger of chemical leakage. Ceramics with sharp edges can be removed and coated with a coating of silicone water-based to avoid damage.

11. Seashells and Corals

Seashells and corals come in different shades. Browns, whites, yellows, and pinks. Reds, pinks, and orange shells can help create your vibrant color scheme.

Seashells create an ocean-like atmosphere in aquariums. Sand pebbles, driftwood, and seashells make a great combination to create gorgeous, natural salt-water aquarium decorations. Boil shells for about 10 minutes prior to placing them in the fish tank.

12. Plants

Aquatic plants thrive underwater which makes them a perfect fish tank decoration. They consume nitrogen and create oxygen, which aids in helping to breathe fish underwater. Place the roots into the substrate to ensure that the plants can thrive and grow. The use of various aquarium plants can make your fish tank appear interesting and natural.

13. Plastic Aquarium Decorations

Unique Fish Tank Decoration Ideas

When you are deciding on creative Christmas fish tank decoration ideas to decorate your home, think about the following aspects:

1. The Size of Your Aquarium

It’s not worth having a lot of big, expensive accessories if your tank gets unorganized and ugly.

It’s pretty stressful for your fish also, if there is little space to move about.

If you’re in smaller tanks it is best to keep things simple. It’s best to pick only a couple of attractive ornaments that stand out, rather than numerous that give your fish very little space to live in.

If you’re having trouble making an informed choice, pick the subject matter that will be used when designing your space. This way, you’ll be able to include decorations such as sunken ships and mermaid kingdoms. It makes it easier to select accessories that are based on an established theme.

Proper Height of Aquarium Elements

Divide your aquarium into 3 zones that are top, middle, and bottom. Fish spend most of their time within any of these three zones, which is why it’s crucial to ensure that there is enough space in each.

To ensure that you ensure that the space is evenly distributed it is recommended to use at least two tall pieces that reach the top area (depending upon the dimensions of the aquarium) and the remaining two or three are small – approximately 1 inch or 2 inches from the bottom of your tank.

Your fish will be more secure If your decorations have the same pattern. With these tips, it is possible to incorporate decorations and other accessories without making your fish uncomfortable.

2. The Color of Your Fish

If you’re worried about disturbing the appearance of your fish tank, then you may stop this by taking into consideration the hue of the fish.

The hue of your ornaments will match or contrast with the color of your fish. If you’re dealing with a lot of lighter-colored fish, a darker background and dull decorations could aid in bringing out the colors.

Fish that are vibrant and bright are great with white gravel and white ornaments and make the hue that your fish catches the eye against the white background. Green plants be a great choice.

3. How Active Are Your Fish?

Highly active fish have a significantly higher intake of oxygen than dormant species.

If you’re keeping these aquarium fish, oxygen-producing decors like bubble chests, bridges, and underwater rivers will help ensure that you have plenty of oxygen, helping to keep your fish healthy and allowing them to stay active.

4. Natural and Artificial. Wild Aquarium Theme

The colors of your aquarium’s accessories will determine the tone of your aquarium.

If you want to create an organic-looking design in your tank, then pea gravel and green, living plants are fantastic choices of colors.

Neon colors and vivid shades can give a wild attractive look that will attract attention to certain parts of your fish tank.

Once you’ve chosen the theme, choose the color of your decor and accessories to be sure they match the look that your tank has.

5. Look Out for Sharp Edges

Decors such as fake plants occasionally come with sharp edges. These could seriously harm your fish by scratching their scales, causing wounds, and opening them for infection.

When choosing the items for the aquarium you want to be sure that you don’t choose any which have sharp edges. which will allow you to achieve a pleasing design without risking the safety of your fish.

6. Consider Focus Points

If you’re planning to add decorations and items to the tank, it may be helpful to choose two or three important focal places.

These elements must stand out from the other decor elements. Mermaid statues and bridges catch people’s attention while setting the scene for your aquarium, and enhancing your overall look.

7. Have Fun, But Exercise Caution When Adding New Things to Your Tank

While it’s possible to become swept away creating a beautiful tank, or adding household items and things that you can find in the wild You should be cautious when introducing something that is new to your fish’s habitat.

Sanitizing Non-Commercial Items

Although store-bought ornaments are usually quite safe, things like driftwood and rocks that are found in nature have to be cleaned prior to being put into your aquarium.

Driftwood needs to be heated or, if it’s not feasible, soak it in salty water for a number of days. Begin by soaking it in hot water, and then it can be removed once it has become overflowing with tannins.

Tannins aren’t harmful to your fish, however, they can lower your water’s KH, and even pH A lot of people aren’t happy that they turn the water brown.

To sterilize rocks or other decor made of hard material, follow this procedure:


  • Buckets
  • Plain chlorine bleach (sodium hypochlorite)
  • Dechlorinator
  • Tap water
  • Cups for measuring


  • I typically suggest doing this with buckets in the shower or bathtub. Be sure to wear clothes that you aren’t afraid of getting bleach on.
  • Mix water and bleach in a bucket in a ratio of 20 parts of water to one part of bleach. For instance, using just 1 cup of bleach you’d have to include 20 cups of water (1.5 5 quarts or gallons).
  • Submerge the items in water and allow them to soak for a few minutes (it can take up to fifteen or twenty minutes for removing the stubborn stain or algae).
  • Get rid of the bleach and rinse the items until they do not smell bleach anymore. Bring the decorations back to the bucket and place them over the water and add a 4-times dosage of the chlorinator. Allow the decor to rest over a period of 10 minutes.
  • Take out the items and dispose of the water. The decor is safe to set inside the tank.
