8. Completing The Look With A Background

When you’re decorating your aquarium, don’t forget about the background. A background is like a big picture that goes behind your fish tank. It can make your underwater world feel even more exciting.

You can choose a background that matches the theme you want for your aquarium. For example, if you want it to look like a coral reef, you can pick a background that shows a coral reef scene. 

If you want a jungle vibe, there are backgrounds with lush jungle pictures. And if you’re going for a mysterious deep-sea feel, there are backgrounds for that too.

9. Going Minimalistic With A Clean Look

A bare-bottom tank doesn’t have any sand or gravel on the bottom. It’s like having a blank canvas. This can be a good choice if you want to create a simple and elegant style in your aquarium.

People often use bare-bottom tanks when they’re breeding fish or if they want to highlight specific fish species. It gives your aquarium a clean and tidy appearance. So, it’s like having a sleek and modern look in your underwater world.

1. Mix It Up With Different Fish

One cool way is to choose different kinds of fish. Think about fish that come in lots of colors and have different ways of acting. When you put them together in your tank, it’s like having a lively and diverse group of friends. 

Some may like to swim near the top, while others explore the bottom. They each have their own special behaviors, and it makes your tank a more happening place.

So, by picking a variety of fish, you create a dynamic and interesting community in your aquarium. It’s like having a little underwater neighborhood with lots of personality.

2. Adding Exciting Lights To Your Aquarium

You can make feeding your fish an exciting event. It’s like having a special mealtime routine. Here’s how you can do it: Every time you feed your fish, use a specific cue, like tapping on the glass or using a special tool. Your fish will learn to recognize this cue as a signal that it’s time to eat.

This is not only fun for you but also interesting for people watching your aquarium. It’s like watching a little show as your fish swim to the cue and enjoy their meal. Plus, it’s a way to teach observers, like kids, about how fish behave and learn.

What Decorations Should Be Avoided?

When you’re picking decorations for your aquarium, there are some things you should stay away from. These are things that could hurt your fish or make them uncomfortable.

1. Avoid Sharp Or Rough Decorations

Don’t use anything sharp or rough in your tank. These kinds of things can hurt your fish. Just like you wouldn’t want anything dangerous in your home, your fish don’t want it in their home either.

So, when you’re picking decorations, make sure they are smooth and safe for your fish. It’s all about making their living space comfy and secure!

2. Keeping Your Aquarium Safe From Harmful Stuff

When you’re choosing decorations for your aquarium, it’s really important to make sure they won’t have anything harmful in them.

One thing to watch out for is toxic materials. These are things that can give off harmful chemicals into the water. Just like you wouldn’t want anything toxic in your home, you don’t want it in your fish’s home either.

So, always make sure that the decorations you pick are safe for your fish and won’t release any harmful stuff into the water. It’s about keeping their environment clean and healthy, just like you’d want for your own space.

3. Don’t Fill Your Tank Too Much

When you’re adding decorations to your aquarium, don’t put too many of them. This is called overcrowding. If you put too much stuff in the tank, it can make your fish feel crowded and stressed out.

So, it’s best to give your fish some space to swim around and not fill the tank with too many decorations. This way, they can have a more comfortable and enjoyable home.

Do Live Plants Serve A Necessary Purpose?

Live plants are not just there to look pretty; they actually do some really important things in your aquarium.

1. Keeping The Water Clean: Live plants help to clean the water in your tank. They do this by taking in a substance called nitrates, which can be harmful to fish in large amounts. It’s like having a natural water filter.

2. Providing Oxygen: Just like we need air to breathe, fish need oxygen in the water to stay alive. Live plants produce oxygen during the day through a process called photosynthesis. This helps your fish breathe and stay healthy.

3. Creating Safe Hideouts: Fish like to have places to hide when they feel a bit shy or stressed. Live plants provide natural hiding spots where fish can feel safe and relaxed. It’s like having cozy corners in your home.

So, live plants not only make your aquarium look beautiful, but they also play a crucial role in keeping your fish healthy and happy. It’s like having both a decoration and a helpful friend in your fish tank!


Decorating your aquarium is like making a beautiful underwater world. You can do this by picking the right things to put in it, creating a fun place for your fish, and making sure they are happy.

Do fish like a lot of decorations?

Some fish enjoy having decorations in their tank because it gives them places to hide, swim around, and explore.

However, it’s essential not to overdo it with too many decorations because that can make the tank crowded and stressful for the fish. It’s best to find a balance that provides both a stimulating environment and enough swimming space.

How do you arrange rocks in an aquarium?

When arranging rocks in an aquarium, think about creating a natural and secure environment for your fish. Place larger rocks at the bottom and build up from there, creating caves, hideouts, and swimming areas.

Make sure the rocks are stable and won’t fall over, which could harm your fish or damage the tank. Take your time arranging them to achieve an appealing and safe setup.

How often should you change decorations in a fish tank?

You don’t need to change decorations frequently unless they become damaged, dirty, or if you want to give your aquarium a fresh look.

In most cases, you can keep the same decorations for a long time, as long as they remain safe for your fish and maintain their appearance. However, it’s a good idea to clean decorations periodically to remove algae or debris that may accumulate.

Can I keep the aquarium in a dark room?

While fish can adapt to different lighting conditions, it’s generally better to have some light in the room where your aquarium is located. Fish, like all living things, benefit from having a day and night cycle.

If you keep the aquarium in a dark room all the time, it might affect its natural behaviors and well-being. So, it’s a good practice to provide some light during the day and darkness at night for your fish.
