Do I Need Fish Tank Decorations?
If you don’t want any decorations in your fishbowl, you don’t have to have them! Decorations purely serve as a visual pleaser and actually have no effect on the life of your fish. However, because of the way they look, many owners love to have decorations in their tank.
The best fish tank decorations can be a fun way to customize and personalize your fish tank so it is completely unique and stands out from the crowd! There are so many different types of decorations out there that your aquarium can pretty much look however you want it to look! They can also create a great aesthetic to increase enjoyment when looking at your aquatic haven.
You could go for a more natural theme with organic decorations, or for a wacky theme with lots of multicolored decorations with different designs, shapes and sizes. The sky is really the limit when it comes to fish tank decoration and this is the reason they are so popular.
What To Look For In The Best Fish Tank Decorations
There are a few things you should take into consideration before choosing and buying your aquarium accessories to make sure they are right for your aquarium and your fish.
Size
Fish need a lot of space to swim around and so the size of your tank is very important when it comes to picking your decorations. You do not want to pick decorations that are too large or have too many of them in the aquarium, otherwise the space will feel very cramped for your fish.
You should make sure that your decorations aren’t concentrated in one space and instead spread them throughout the tank. This will also give your fish more room to move around in. Try to stick to the 2:3 ratio rule — for every two tall structures, you should have about 2 or 3 medium structures to balance out the space.
Natural vs. Non Natural
Whether you choose natural or non natural decorations is completely up to you and does not affect your fish or their life at all. It will be down to you to pick whether you want your tank to have a more natural feel or to be a bit more out there with interesting structures and colors! Natural decorations include wood, plants and gravel and will mimic a natural habitat, while non natural decorations can be very different and certainly draw the eye!
Color
The colors you choose to have in your fish tank go hand in hand in, whether you want a more natural feel or not. If you do want a natural feel, you will stick with decorations that are brown and green in color. If you want something that really pops, you could go for bright colors that stand out, and you can even add to that with colorful fish tank gravel too.
The color of your fish is something to take into consideration. If you have multicolored fish then you might want to go for a plain background with plain decorations, such as the color white so they stand out more. If your fish are darker, you could go for neon colors so the tank really stands out against them.
Plants
Aquarium plants are beneficial to any fish tank. Not only do they look cool and make the tank look more authentic, but they more closely mimic a natural habitat for your fish as they will be able to brush up against them.
Live plants are particularly beneficial to a fishbowl because they add oxygen to the water and remove carbon dioxide/ammonia. They can also help to reduce algae growth, but they do take a lot of time to maintain and keep healthy. In many ways they are the best fish tank decorations as they work well to maintain your water and tank.
Artificial plants, on the other hand, come readily set up and are available in many sizes and colors. They, of course, do not have the benefits of live plants, but are very easy to maintain. It is up to you whether you decide to choose live or artificial plants.
