Do you want to adopt a pet but don’t know what to get because it’s your first time? 

Might we recommend bringing home betta fish? That’s right; these fish have gorgeous colors, are low-maintenance, and are extremely entertaining. 

But you might be wondering – “how much does a betta fish cost?” So, we’ve highlighted all the possible expenses in our guide to help you plan accordingly.  

Initial Costs To Own One Betta Fish

Get a Betta Fish from Adoption 

There are two ways to own a betta fish: adoption or contacting a breeder. Let’s discuss the former because it’s a cost-effective method; plus, you might be able to look after an injured fish. 

After people find fish in bad shape, they are sent to the rescue to nurse them back to life. Now, we know it’s not ideal, and most owners want a healthy pet for their homes. 

But there are very few things as fulfilling as watching the once injured fish swimming happily around the tank. So, you can reach out to local rescues to see if they have any betta fish, which will cost you only $5-$10.  

Purchase a Betta Fish from a Local Breeder 

If adoption is not an option, you can contact a breeder to bring home a healthy and colorful betta fish. But you should know that going to a breeder has its advantages and disadvantages. 

For instance, you’re likely to find fish of rare colors that aren’t available in pet stores. On the flip side, they cost more because of this very reason; most breeders sell betta fish for $15-$30. 

But rest assured, the price will be well worth the investment, provided you have all the supplies for taking care of them. 

Initial Setup And Supplies 

Let’s discuss supplies next as you’ll need to purchase proper equipment for the initial setup of your aquarium. It includes everything from choosing the correct tank size to other fish-related products that you might find at stores like PetSmart. 

Now, you’ll have to purchase the tank a few weeks in advance and keep it ready with the aeration system, filters, heaters, and decorations to begin the cycling procedure. This will help establish the nitrifying bacteria for when you introduce the fish. 

Overall, the entire process should cost between $100 and $200 for a 5-10-gallon tank.

Total Monthly Cost

Although the initial setup cost is quite steep, taking care of betta fish isn’t expensive. They are extremely low-maintenance, and the major costs you incur will be related to medication, food, and other underwater features that you might add. 

Understandably, pet owners’ total cost per month will vary but shouldn’t be more than $60. In some cases, buying water conditioners and food packets in bulk will save you the hassle of making frequent purchases. 

Not to mention, it can help reduce costs to as low as $20 since there is no need to buy a lot of external supplies. 

Health Care 

Despite constant care and attention, there is always a chance that the betta fish may experience health issues. Meaning, your primary concern should be to maintain the water quality, ensuring that they have a long life. 

You first need to purchase a premium-quality water conditioner from Petco to keep the tank chlorine-free. In some cases, these devices also remove heavy metals, ammonia, and nitrate to prolong the longevity of the plumbing system. 

Now, the best water conditioners usually cost $25-$40, but you can buy a cheaper product as well. Just be careful that the watercolor doesn’t change after a cleaning session. 


Most aquarists will tell you that the betta fish reach a maximum length of 3 inches, so they don’t require much food. They are mostly carnivorous, but you can feed them eatables like flakes or pellets. 

We found that the average monthly cost to feed betta fish varies between $10 and $20. However, if you manage to feed them live bait, the cost will go down further. 

We recommend that you feed them a protein-rich betta fish food consisting of, but not limited to, tubifex worm, blood worms, and brine shrimp. Sometimes, people also use insect cultures to provide the fish with a steady supply of nutrients. 


Remember how we spoke about healthcare? Well, you need to be prepared to deal with betta fish emergencies. That means having the necessary medication close by to treat various ailments. 

The cost of treatment depends upon the severity of the disease and the type of betta fish you have. In most cases, the expenditure varies from $15-$50 per month, and it’s possible to buy the medicines from any certified store like Petsmart or Petco. 

That said, be careful while adding them to the water because a powerful dose could remove carbon from the filters and kill beneficial bacteria. 


You’ll be pleased to know that betta fish are entertainers and often learn to perform tricks. You can therefore add toys to the tank to keep them engaged so that they remain healthy. 

For example, an extremely simple toy that aquarists can use is a mirror. When the fish look in the mirror, they get the impression of staring at a rival, causing them to stretch and flare their muscles. 

Other than that, you can place leaves inside the tank, which will act as a resting spot. So, all things considered, most toys are simple and cost $5-$20 per month. 

Final Thoughts

Hopefully, our guide has answered your queries so that you can take care of different betta fish varieties. 

Before signing off, we’ll leave you with this tip: buy a separate tank for keeping the fish while you’re cleaning the main tank. The former will also come in handy during the mating season.

Rest assured, with the right care, betta fish will brighten up your home, thanks to their vibrant colors. On that note, we’ll conclude our proceedings for today.
