How to Set up a Beautiful Betta Fish Tank

Congratulations on getting your new betta fish! Betta splendens is one of the most stunning, beginner-friendly fish out there, so of course he needs to have a beautiful aquarium to match. Our recommended shopping list and setup tips will help you give your betta the warmest welcome.


Betta Checklist: Everything You Need for Your New Fish

Let’s start shopping for the components needed to set up your betta fish’s new home. All of these items can be easily found at your local pet store or online.

5-gallon tank

It is the perfect size to start with a single bettafish. Many people mistakenly think that betta fish can live in small containers. But a dog who can survive in a kennel all their life would not prefer to live in a larger house or yard. A bigger aquarium gives your betta fish the freedom to swim around and explore his environment. You will also notice a cleaner aquarium for a longer time.

A small 0.5-gallon tank may need to be refilled every day, while a 5-gallon fish aquarium can last for up to two weeks.

Betta fish are well-known by the nickname “Siamese fighting fish” because of their aggressive behavior towards their own species. All bettas, male and female, should be kept separately. In fact, betta sororities (or an aquarium with all female bettas) are not recommended except for the most experienced fish keepers. The good news is that betta fish can be kept in a larger community tank with other types of fish, so check out our list of suitable tank mates.

How to Set Up a Betta Tank

Now that you have all your supplies, here is a step-by-step guide to assembling your aquarium:

1. Pick a good location. The aquarium needs to be near an electrical outline for the equipment and a source of water for easy tank maintenance. Avoid areas that are directly in sunlight, or near the heating or air conditioner to reduce temperature fluctuations and algae growth. Finally, remember that your aquarium is likely made of glass or acrylic, so select a spot where the tank will not get hit or crashed into because no one wants 5 gallons of water leaking all over the floor. 2. Use a good aquarium stand. Fish tanks are surprisingly heavy (close to 10 lbs. You can expect to pay about 10 lbs per gallon for water and supplies when your aquarium is full. The stand must be water-resistant so it doesn’t crack over time. 3. Wash the supplies. Use warm water to rinse the tank, equipment, substrate, and decorations to remove any dust and debris. Do not use any soap or cleaning detergents, since they may be harmful to your fish. If you purchased a used aquarium, you may want to check for leaks by letting it sit full of water for 24 hours and looking for signs of dampness. 4. Install the supplies. Now it’s time for the interior design! Install the equipment in the aquarium (without plugging them in yet) and then position the decorations around them in a pleasing manner. You can hide the filter by placing ornaments or plants next to it. This will help reduce the current for betta fish. 5. Add water. Fill the tank up with tap water. Add a dechlorinator for the removal of toxic chemicals and chlorine. The filter can now be plugged in, but most heaters require you to wait 30 minutes before turning them on (in order to acclimate to the water temperature). For more information, including how to add drip loops for power cables, refer to the equipment manuals.

One of the most common questions we receive is “Do bettafish need a cycled aquarium?”. So, if you don’t know what the nitrogen cycle is, read this article on how to “cycle” an aquarium.

Welcoming Your New Betta Fish

The final step in setting up your aquarium is of course adding your new betta fish. You don’t need to give preventative medication if he is the only fish in your aquarium. Most betta fish bought from pet shops have been kept in isolation their entire lives. Simply float your betta’s little container or bag in the aquarium for 20 minutes so that the temperature in his bag matches the temperature in the tank. Then let your betta into his new home without adding any of the fish store water into the aquarium – either by scooping him out with a net or draining all the old water first.
