This blog post will discuss five of the most creative and inspiring ideas for your small fish tank. Read on to learn more about how to give your fish tank an upgrade!

The Betta Bowl

The Betta bowl is trendy for those looking to keep a small Fish tank. Betta fish are some of the most beautiful, vibrant fish available in the aquarium hobby, and the best part is that they don’t require much space. 

A Betta bowl is usually relatively small, ranging from 2 to 10 gallons in capacity. When selecting a bowl for your betta, the critical thing to remember is to ensure enough room for your fish to move around comfortably.

Bettas require good filtration and regular water changes, so make sure you have a suitably sized filter for the size of your bowl. Additionally, you should use a heater to keep the water warm, as Bettas prefer warmer temperatures. 

You can add some live plants or even floating silk plants to your bowl to add some decoration. Finally, ensure your Betta has plenty of hiding spots and places to explore. A Betta bowl can be a beautiful addition to any home with the proper setup!

The Centerpiece Tank

The centerpiece tank is a great way to make your fish tank stand out and be the room’s star. This tank usually contains a large, single fish species as the main attraction. 

These tanks require an experienced hobbyist to keep the fish healthy and thriving, but if done correctly, they can provide an eye-catching focal point for any space.

When choosing a fish for the centerpiece tank, select one that is relatively low-maintenance and isn’t too aggressive. Some good choices include Angelfish, Gourami, Seluang, Tetras, or small Cichlids. 

In addition, It is essential to provide regular water changes and test parameters to ensure that the water quality is at optimal levels for the fish. However, adding supplemental food such as frozen brine shrimp, bloodworms, and algae tablets can help the fish stay healthy and strong.

Finally, the centerpiece tank should be around 30 gallons or larger, giving your fish enough room to swim and explore their environment. The tank should also have plenty of places for the fish to hide, such as rocks, driftwood, and live plants.

Adding too many decorations can make the tank seem cluttered and cramped, so create an open area with plenty of space for your fish to move around. 

With the right size, fish, decorations, and open swimming space, you can create a fantastic centerpiece tank that will be the star of any room!

The Shrimp Tank

A shrimp tank is ideal for those looking for a low-maintenance fish tank, and they require very little maintenance and are suitable for small spaces. Shrimp tanks can come in all shapes and sizes and be custom-made to fit into your home décor. 

Shrimp tanks require less water than most fish tanks and can be easily managed with minimal effort. However, when stocking your shrimp tank, you must ensure the species you choose to get along. 

Shrimp come in various sizes and colors to create a beautiful and unique display with a mix of different species. Some popular shrimp species include cherry, amano, bee, and ghost shrimp.

Finally, you must select the right type of food for your shrimp. Many types of specialized shrimp food are available, but you can also feed them vegetables and blanched peas.

Whatever food you choose, ensure it is rich in nutrients and not too high in protein. With the right supplies and knowledge, setting up a shrimp tank can be an exciting and rewarding experience. 

The Nano-Planted Tank

A Nano-planted tank is an excellent choice for those looking to add aquatic and plant life to a smaller space. 

You can create a vibrant, lush, colorful aquascape in even the tiniest aquariums with careful maintenance. Nano tanks typically range from 5 to 30 gallons and generally are taller than wide

As such, they require intense lighting to reach all tank areas. Depending on your choice of plants, you may need LED lighting or specialized plant bulbs. You’ll also need to pay attention to your substrate and ensure it contains enough nutrients for healthy plant growth. 

Due to the size of the aquarium tank, all related components were designed for a smaller system. Nano aquarium lights, nano aquarium filters, nano aquarium heaters, and nano aquarium stands are included in this category.

Filtration is another crucial aspect when setting up your nano-planted tank. Small tanks can quickly become overwhelmed by waste and debris, so choose a filter appropriate for your tank’s size.

Also, when designing your nano-planted tank, you’ll want to focus on providing plenty of hiding places for your fish and plenty of space for them to swim. Live plants can be used, though many people opt for plastic plants due to their easy maintenance requirements. 

Whether just starting a hobby or looking for a unique challenge, nano-planted tanks can be an enjoyable experience!

The Goldfish Bowl

The goldfish bowl is an iconic fish tank that has been around for generations. This classic look consists of a large glass bowl that can house a single or small group of goldfish. 

While this tank style is not ideal for long-term goldfish health, it is a stunning decorative piece in any home. Water quality is the most important thing to remember when setting up a goldfish bowl. 

Goldfish are very sensitive to ammonia and nitrite levels, so having a powerful filtration system is essential. Regular water changes will also help to keep your goldfish healthy and thriving. 

You should also avoid overcrowding the tank, as it can lead to stress and increase ammonia levels. Adding some live plants and decorations to the bowl will also help to provide oxygen and a natural place for your goldfish to hide and explore. 

Finally, when it comes to stocking a goldfish bowl, choose wisely. While most people think of fancy goldfish as the only option for this type of tank, there are many other options. 

Small school fish like White Cloud Mountain Minnows or Neon Tetras can significantly add to your goldfish bowl setup. Ensure you’re not overcrowding the tank and providing adequate filtration and regular water changes.


Fish tanks can be a great addition to any home, providing aesthetic and educational value. Whether you’re looking for an easy maintenance tank or an advanced one with lots of plants and creatures, there is something out there for everyone. 

The five options outlined in this blog post are all great starting points for the small aquarium enthusiast. Do your research, find the right fit, and watch your aquarium come to life!
