9 Best Aquarium Decorations for Aesthetic Appeal of Your Tank (15)

When making the final buying decision for your aquarium decors, the following considerations can be of big help to especially aid you pick the most appropriate product for you:

Calculate the size of your fish tank

For sure, you wouldn’t prefer to make your aquarium look crowded as this would only suffocate your pet fish and can make the tank look messy. Only buy the ones that are adequate enough to provide an impressive overall look for the aquarium and can still offer sufficient space for your live creatures to move, play and swim around inside the tank.

Once you are already well aware of the size of your fish tank, the next thing for you to decide on is the theme you prefer to design in your aquarium. Over-decorating your tank would only make it look cheap so be sure that you have a set theme in mind prior to buying the decors. Just concentrate on a specific theme to avoid clutter.

By the same token, the color of your adornments would be the one to set the theme for your fish tank. If you wish to come up with a natural-looking theme for your aquarium, live green-colored plants and pea gravel make ideal options when it comes to color.

Meanwhile, vibrant shades as well as neon hues could make a wilder, more flashy and more captivating look to certain spots in your fish tank. Once you have made up your mind on a certain theme, carefully pick the color of the embellishments and accessories to complement the overall feel of your aquarium.

Check out the proper height of fish tank elements

To do this, you can start by separating the aquarium into 3 sections: bottom, center and top zones. The reason behind this is that fish are more inclined to spend more of their time in any of these 3 sections; hence, it is imperative to keep some rooms free for each zone.

Take into account that fish tend to feel safer and more comfortable if the decors adhere to some sort of structure. See to it balances the space available in a fair approach. This way, it will be easier to consolidate embellishments as well as accessories without making your pet fish feel distressed.

Think about the color of your pet fish

You can complement or ruin the entire look of the aquarium if wrong color is selected. If the color of your décor and your fish don’t blend well, what do you think will be the end result of your decorations? You can ask for some advice or suggestions or look for some samples if you are not that adept at matching colors.

Do you keep active fish?

Super active fish tend to have a remarkably superior oxygen uptake as compared to inactive ones. Thus, if you are taking care of such fish, oxygen-producing adornments such as bridges, underwater chests and bubble chests could assist in offering generous amounts of air so which helps in keeping your pet fish to stay highly active and healthy.

Keep an eye on sharp edges

Adornments such as artificial plants come with sharp edges at times. Evidently, these could badly endanger your pet fish by creating injuries, scratching their scales and making them prone to serious infections. When selecting embellishments for your fish tank, make certain that you stay away from any options that come with sharp edges. You can still beautify your tank without endangering the safety of your pet fish.

Mull over on focal points

When adding adornments to your aquarium, it could be practical to choose 1 or 2 focal points. Such points must be capable of being more prominent among the other decors to complement your overall design.

Other Important Factors to Consider

9 Best Aquarium Decorations for Aesthetic Appeal of Your Tank (16)

What is an aquarium decoration? How does it work?

Fish tank decors consist of natural and artificial adornments that are specifically designed for marine and freshwater applications. These embellishments usually consist of different backdrops and substrates utilized with tanks. Decors are generally labeled as for fish only and others are for fish only with live rocks.

When it comes to reef tanks, corals commonly serve as their very own kind of aquarium adornment. Decors for aquariums work by acting as safe shelters for many fish species. For instance, live rocks serve as organic bio-natural filters and are not only meant to offer aesthetics to the overall look of the tank. They teem with various sorts of macro and microorganisms plus other bacteria that execute a good job of cleaning the tank water.

In substance, the decors utilized in your fish tank could affect not solely the manner your aquarium looks but also how your pet fish unite with the elements in the aquarium. Adornments for tanks could offer your pet fish a lot of zones where they could hide and some spots that they could consider their territory.

What are the different types of aquarium decorations?

Aquarium decors comprise or organic materials that include wood, rocks and corals. These decors are usually exploited in setups that have been arranged to appear as organic as feasible. Substrate and plants that are identical to sandy bottoms are also used.

In line with this, there are also artificial decors used for fish tanks and they look realistic as well. Examples of fake tank adornments include coral replicas, artificial plants and anemones that are quite famous for marine applications. If you are a novice in keeping a saltwater tank, it is highly suggested, to begin with a fish-only tank and utilize artificial anemones and corals as decors. This is because anemones and corals are difficult to look after and they come with very specific requirements.

Apart from organic or organic-looking tank decors, there is also a broad array of tank adornments that would naturally be uncovered in oceans, rivers and lakes. Examples of these include shipwrecks, bones, sculls and a lot more.

Bear in mind that it is a must to use decors for fish tanks that are specifically manufactured or designed for aquariums. Go for saltwater-safe options if you are currently keeping a marine tank. The same goes if you are keeping a freshwater tank; opt for freshwater-safe decors to avoid the emergence of hazardous organisms, the possibility of injuries and other unfortunate incidents.

Frequently Asked Questions

9 Best Aquarium Decorations for Aesthetic Appeal of Your Tank (17)

Do fish like more or less decorations?

Fish don’t have a preference for more or fewer decorations. The key is more about offering enough decorations without making the tank overcrowded. So if you have a small 5-gallon or 10 gallon fish tank, don’t have 20 decorations.

Basically, it would be setting up a dangerous environment just because it looks pretty. These overcrowded settings can cause a significant amount of issues for fish. It’s why finding a balance is essential.

After all, a high-quality fish tank decoration set can help create a relaxing atmosphere. You can even use them to build a similar environment to their natural one. Your fish will adapt and thrive in their well-crafted tank if you follow the 50% coverage rule.

How can I make my aquarium attractive?

My first recommendation would be to think of themed fish tank decor ideas. Crafting a usable theme inside an aquarium is the easiest way to make your aquarium more attractive. You can then make purchases and decisions based on that singular idea.

Once you have a theme, consider what fish best mesh with it. You don’t want a color palette of fish that doesn’t blend in with your overall theme. It’ll become an eyesore and a disaster to the overall decor.

Your next step will be choosing bright, colorful gravel to incorporate into the theme. Of course, please don’t choose a non-matching color or it’ll have the same impact as the wrong fish type. Also, make sure your chosen breed likes hardcover; if it doesn’t, opt for soft cover like plants instead.

Lastly, choose some funny and creative decorative items to spice up the enclosure. If none of the ideas mentioned in this article intrigue you, there’s plenty to select from on sites like Amazon or Chewy. Etsy also has cute custom fish tank decorations to bring your tank to a new level.

What decor is safe for a fish tank?

Aquarium hobbyists have a lot of choices when it comes to tank design ideas. In fact, you can put almost any aquarium decorations inside a tank. The only caveats are it must not release toxic chemicals, have sharp edges, or affect the water.

If it meets these criteria, don’t hesitate to place it inside your fish tank. It doesn’t matter how unusual the item might be as long it follows those rules.

Usually, any decoration made from ceramics, glass, or plastic is acceptable. I’ve certainly had fish tank centerpieces made from all these within my 55 gallon tank.

Just as importantly, make sure the decor you choose cannot be chewed by fish and choke them. Avoid items with soluble metals and dyes as well.

What decorations are fish more attracted to?

Most decorations inside a fish tank will be about creating your wanted aesthetic. But fish do like certain ones more than others. In particular, aquarium items with built-in hiding spaces must have inclusions in fish tanks.

These hiding spaces provide a way for fish to get privacy. In addition, it makes them more comfortable and relaxed within these enclosures. Therefore, don’t create an aquarium environment without accounting for some decorations like rocks, plants, and driftwood.

What are the most trusted aquarium decoration brands?

Admittedly, it could be overwhelming to make the final buying decision when you are offered limitless choices to select from. Since you can come across lots of different decorations for aquariums, it could sometimes be confusing which one to get because nearly all of them look stunning, are not that expensive and designed with vibrant and attractive colors that are too good to resist.

On the other hand, not all of them are created equal. Each of them comes with pros and cons. So, for you to end your agonies whether to get a certain fish tank décor or not, it is wise to do a little research regarding the manufacturer of the product.

As you know, when a product is manufactured by a world-class and famous brand, the product is more likely filled with incredible features making it a reliable and functional product to invest in.

How to set up?

Are you wondering how to set up various decors for aquariums properly? Then, you may consider the following guides to set up some decorations in your aquarium correctly:

  • Position larger plants and other adornments toward the edges and rear sections. Meanwhile, the shorter decors must be placed toward the front section. There should be enough space where your pet fish can freely roam, swim and play around.
  • Utilize taller plants or adornments to conceal air lines, fish tank heaters, and lift tubes and other undesired items of the aquarium.
  • Be sure to utilize fewer variants of decors to make the aquarium appear more natural as possible. Exploit groupings of the identical form of plants and readjust them with plant groupings with a distinct texture or color in order to form a more attractive space.
  • It is highly suggested to utilize smaller rocks or plants to obscure the edges of water wheels, ceramics, castles, plastic adornments, resin, and volcanoes to make them appear more organic and authentic inside the aquarium.
  • Choose one or two focal plants or adornments and position them a little off in the middle inside the aquarium. Centered decors usually appear awkward or constrained.
  • Always set a nice backdrop. This could offer a very firm or dark wall for your pet fish and this could aid them to feel more comfortable. The backdrop is also meant to aid conceal pipes, cords, filters and tubes that could discredit the entire look of your aquarium.

Fish tanks absolutely provide peaceful scenarios and it cannot be denied that the relaxing sounds of bubbling water that harmonize with any home’s adornment style are simply irresistible. As the main attraction for any space or in any room at home, aquarium keepers could place large aquarium adornment pieces inside the tank to help make it engrossing and be capable of providing your pet fish a safe and comfortable spot to hide.

How to properly clean and care for tank decors?

  • Use scrub brushes that come with soft bristles; also consider purchasing a gravel wash kit and pad scrub pads that are soft to use when cleaning the tank decors.

See to it to buying products that are specifically designed for your aquaria and consider the fact that you need to be extra careful when cleaning acrylic aquaria because these are more prone to getting scratched easily as compared to glass aquaria. Do not utilize a rough pad or rough brush on an aquarium made of acrylic.

  • Gently scrub off the algae buildup and other accumulated dirt particles on the aquarium’s walls or edges. When scrubbing adornments, you may utilize hard-bristled brush. On the other hand, when dealing with the tank’s walls, you can use soft pads that are designed with long handles.
  • At the time the algae buildup and other plied up dirt were thoroughly scrubbed off, it was high time to replace the tank water.
  • When cleaning the substrate, the water should also be removed.

When cleaning the substrate, consider using a gravel wash tube that is designed with a bendable hose that has the capability to go easily into a canister. This tube as well as the tube suction is meant to clean up the gravel and lift the dusky water, debris and fish excrement by means of the tube and into the canister.

  • The frequency of cleaning the gravel will largely rely on many factors. Consider the number of fish you are keeping in the tank, ask yourself if you are guilty of overfeeding your fish and if you added live organic plants in the tank that are prone to losing leaves.

Please take into consideration that although your aquarium comes with exceptional quality of water, it is indispensable to execute tiny gravel washes on a weekly mode in order to get rid of excess debris, food waste and fish excrement.

Basically, tidying the adornments in your aquarium will help keep your fish tank dwellers active, happy and healthy. And, a clean tank will always be quite impressive to behold.

What is the warranty?

Over and above, buying products that are supported by different forms of warranties is the best choice because they provide every customer the kind of protection they deserve whenever they go shopping locally or online.

It is a must to opt for aquarium decors that come with warranties so that in case you encounter some issues with them, you can address the problem right away and have the solution you especially require after receiving the item.

This is why buying from trustworthy brands is a wise thing to do because they generally sold products that offer various types of warranties that you can avail of.

Where to buy?
