As the saying goes, you can’t have your cake and eat it too, but that clearly doesn’t apply to the world of wizarding. What I’m saying is, you might not think that it’s possible to make your fish tank festive with Harry Potter themes and still have healthy fish, but that’s not true.

Get Your LEGOs Out
Believe it or not, LEGOs are safe for fish tanks as long as you take a few precautions. Before adding LEGOs to your 55-gallon fish tank, ensure they are cleaned and free of harmful chemicals.
Depending on what lego sets you to have, you can create all sorts of different underwater scenes. The Disney sets, for instance, enable you to transport the classical characters into an underwater world. Or if you’re feeling a little bit more adventurous, check out the LEGO Mario set – perfect for creating an action-packed aquarium scene.

This one is for all you Pixar fans out there. Unfortunately, these charismatic “fish” in the film “Finding Nemo” and its sequel “Finding Dory” wouldn’t get along in a real-life 55 gallons aquarium, as they require a lot more space .
The good news is that we can still create a similar tank that resembles the one from these popular films. All you need is colorful and bright gravel, a “busy” coral background, Disney stickers, and some fun aquarium ornaments of your favorite “Finding Nemo” and “Finding Dory” characters.
Keep the Peace
Let’s face it: For many of us, the aquarium is somewhere we can go to feel relaxed and at peace after a long day, so why not create a zen-like environment that embodies those feelings?
This type of aquarium is all about simplicity and can be created with just a few key elements. To design a tranquil zen garden in a 55-gallon fish tank, add in light-colored gravel, live plants that have tall, slender leaves, stone caves, as well as a Buddha statue to balance everything out.
Be sure to keep a close eye on your arrangement. After all, the fish’s needs are always our #1 priority.
Amazon River-Themed aquarium
If you’re the kind of fish keeper who likes to recreate an Amazonian biotope tank, with plenty of Sumatra wood, pale sand, Indian Almond Leaf, and majestic Altum angelfish, you might love the idea of a natural Amazon River-Themed aquarium.
This type of themed aquarium is not for the beginner for two main reasons. Firstly, angelfish is a very delicate species that require a lot of care. Secondly, you will need a blackwater effect that looks natural, but not so intense to spoil the entire view. The latter requires the aquarist to have extensive knowledge regarding water chemistry and the necessary filtration system to maintain it.
African Great Lakes Biotope Aquarium
Last but not least, the 55-gallon fish decor idea on our list is the African Great Lakes Biotope Aquarium. As you can imagine, this themed aquarium is perfect for those passionate about African cichlids.
Most magnificent African cichlids aquariums are characterized by a rocky landscape with plenty of caves and crevices. The rocks are usually arranged in a way that forms terraces and swim-throughs, providing the fish with plenty of places to hide and explore. The lighting should be bright to bring out the colors of these beautiful fish.
Aquascaping 55 Gallons Fish Tank
While a 55 gallons fish tank is not the perfect size for aquascaping because of its limited depth, it can still be done with creativity.
Iwagumi (Nature) Aquarium
Iwagumi is one of the four main styles of Nature Aquarium. The other styles are Ryuboku, Mizube, and Ragwork.
Since Takashi Amano , the author of Nature Aquarium World, introduced the Iwagumi style of aquarium design in the 1980s, it has become one of the most popular ways to aquascape in the freshwater planted aquarium hobby.
An Iwagumi aquarium typically contains two main types of decorations: rocks and plants. The most defining characteristic of this style is its stripped-down nature. That’s why it’s called a ‘rock garden’ in Japanese.
An Iwagumi aquascape design is simpler to achieve in an aquarium that’s wider from front to back than tall. If you’re set on this style in a 55-gallon fish tank, your best bet is to use smaller rocks and arrange them closer together.
Mixing only species of display fish into the design can be a special way to complement the natural beauty of the aquascape.
Interested in setting up an Iwagumi aquarium? Check out these two dedicated guides:
Another major aquascaping style in the aquarium world. Similarly, the Dutch Aquarium style does not rely on hardscape materials, such as rocks or wood, and instead focuses on various aquatic plants.
In contrast to other types of aquariums, Dutch aquarium planting is commonly recognized for its high density, strong color contrast, and delicate texture.
The challenge of replicating a Dutch Aquarium in a 55-gallon fish tank is to create a sense of terracing using plants.
Terracing is an efficient way of creating focal points in your landscape design. This can be done by following the rule of thirds, which says that the viewer’s eye will naturally be drawn to one-third of the image Plane. In Dutch aquascape designs, red or large plants are usually used to draw attention to the focal point.
Here is a gorgeous 55-gallon Dutch aquarium for your inspiration.
Contrary to popular belief, the Jungle-style aquarium looks harder to accomplish because of the heavy plant growth, but the fact is that it’s possibly the easiest type to replicate.
Just as the name may suggest, this style of aquascape is defined by its various vegetation of a wild and untamed setting. The goal is to create an underwater jungle with a variety of different plants, both tall and short.
Different from the well-trimmed Iwagumi aquascaping style, a Jungle style mainly harnesses the natural growth of live plants; therefore, it does not need everyday trimming. Nonetheless, both types of aquascaping require deep research on which plant species will give your tank that desired effect.
If you want to go for the Jungle feel, here are ideas of what to do with your 55-gallon fish tank.

schooling fish and snails. Of course, the possibilities are endless, and you can always get creative with your 55-gallon fish tank.
Now you are equipped with 55-gallon fish tank ideas and different types of aquascaping styles. It’s time to decide which is your favorite and start replicating it in your own 55-gallon fish tank.
