How Much Do Bettas Cost?

Tank (5-gallon or larger preferred)

Betta marketers have long shown this species in small fish bowls. Unfortunately, this is an advertising method that makes it seem like Bettas prefer smaller tanks, which is not the case.

We recommend a 5-gallon tank or larger to allow proper room for water regulation and for your Betta to flourish.

Tank Hood/Light

The average Betta can jump 2-3 inches out of the water, so you’re going to need a tank hood. If this hood has an adjacent light, it can make it easier to both see your Betta and showcase the tank in your home.


Bettas are tropical fish that need to live in water that is between 75°-80°F. Anything colder could lower their immune system, making them prone to illness. Higher temperatures can increase their metabolism, aging them faster.

A water heater is essential to keep your Bettas alive and thriving.


A Betta in a tank without a filter is like a human stranded on a lifeboat in the sea – both can survive for some time, but both will be miserable, sickly, and die a premature death.

Filters remove the tank’s dirt and toxic buildup, as well as aerate the water so your Betta can breathe easier. Save your Betta from the lifeboat, and be sure to buy a filter.


The most popular underlying layer for a tank is gravel, although some people may opt for pebbles or glass marbles. Gravel is the most sanitary option of the three, especially if you’re using a mini siphon to clean the bottom of your tank.


Live or plastic plants are a great addition to your Betta’s fish tank. Bettas like to hide or sleep between plant leaves, so this creates a safe space for your pet. If you opt for live plants, they will enhance the water quality and produce more O2 for your fish.

Either option will enhance your tank’s beauty and practicality.


Choose decorations that are specifically made for fish tanks. This could include driftwood, cartoon characters, hiding spots for your Betta, or anything else to enhance your tank’s style. Make sure to also leave enough space for swimming, of course.

Digital Thermometer    

You won’t know if your heater is working unless you have a way to test the water’s temperature. Purchase a small digital thermometer that can be stuck right on the inside of your tank, and you’ll be able to regulate the water temperature daily.

Mini Siphon

A mini siphon is a tool used to remove uneaten food from inside an aquarium. Using a natural suction method, a mini siphon will capture particles in your water and remove them out of the other end of a small hose into a sink or bucket.

Betta Fish Tank & Accessories Costs

Now that you know what you need, let’s have a look at the price range for each piece of equipment and accessory piece.

Tank (5-gallon or larger) Price

A 5-gallon fish tank can run anywhere from $20-$100, depending on the model, inclusions, and store. More expensive tanks may already include some additional equipment or decorations and can be vertical instead of horizontal.

If you’re just looking to buy the tank without add-ons, a great option would be to check out second-hand tanks for sale on Craigslist, Facebook Marketplace, or other online markets.

Heater Price

The heater you purchase will depend on how much water is in your tank. If your tank is less than 3 gallons, you can find a mini-aquarium heater for as low as $8.

If you have a 3-10 gallon tank, the price rises to around $16. More expensive heaters may include their own digital thermometers.

Filter Price

You can find basic aquarium filters for between $18-$25. Most of these include quiet technology to make the lowest amount of noise possible.

Gravel Price

You’ll want between 1-2 inches of substrate on your aquarium floor, which is roughly 1 pound of gravel per gallon of water. Aquarium gravel runs at about $1 per pound, but most bags are sold at 5-pound intervals.

Plants Price

The plant cost for your tank depends on if you’re using real plants or artificial ones. The former’s price depends on the type of plant and can range from $2-$20 per plant. Artificial plants typically run from $1-$10 per plant.

Decorations Price

When it comes to aquarium decorations, the world is your oyster. Prices range wildly depending on which decorations and how many you want in your tank. Most ornaments, driftwood pieces, and rock designs cost between $6-$22 each.

Digital Thermometer Price

If it isn’t included in your heater, you can purchase an aquatic digital thermometer for as little as $6.

Mini Siphon Price

A mini siphon for your aquarium also costs around $6. If you have a 15+ gallon tank and opt for a full-size siphon, you could spend between $10-$30.

Regular Cost of Maintaining Betta Fish

Betta fish are much more economical to maintain compared to other pets like dogs, rabbits, or snakes. Even so, you’ll need to account for the prices of food, electricity, water, vacation preparation, medication, and tank maintenance.

Betta Food Cost

Bettas are carnivorous and should be fed a diet that is high in protein. It is not enough to simply give them dry fish food, as their color thrives from a diverse diet.

If combining dry food ($3.99 for a 7oz. container) and wet, such as frozen or live blood worms, it could cost you between $4-$10 per week.

Electricity Cost

Your Betta tank will be running 24/7, which means you’ll be spending electricity on the heater, light, and filter. Electricity costs vary depending on the location and wattage used.

A generalized 5-gallon tank with a 50-watt heater, 5-watt filter, 5-watt light for viewing (no live plants), and 2.5-watt air pump could use around $2 worth of electricity per month. If you’re using a powerhead or stronger light to support live plants, this price will increase.

Water Cost

A gallon of water in the U.S. currently costs less than 1 penny per gallon, which means that your Betta’s water cost will only add on a few cents to the total cost.

Vacation Preparation Cost

If you often travel for more than a few days, you’ll need to hire someone to take care of your Betta fish. Fish blocks created for this purpose often include ingredients that are hard for Bettas to digest, so you won’t want to rely on this method often.

Medication Costs

If given the wrong diet or exposed to low temperatures, a Betta fish can get sick. The most common illnesses for Bettas are fin and tail rot, columnaris, and hemorrhagic. All are treatable with antibiotics which can cost around $15.

Tank Maintenance

With routine maintenance, you can preserve your tank for years to come. This includes regular water changes, servicing the filter, and testing the aquarium water.

If you have a chemical filter, this will need to be changed once per month, but biological filters are preferred and don’t require this step. Water test kits cost about $1 per kit to be used at least once a month.

How Much Does a Betta Fish Cost with All Supplies and Accessories?

Calculating the total cost of owning your pet Betta depends on your tank, shopping preferences, types of plants and decorations, Betta’s diet, and your lifestyle. We’ve broken down the basic price brackets below, depending on your preferences.

Total Cost for Economical 5-Gallon Tank

A 5-gallon tank purchased second-hand, with one common Betta fish, 3 artificial plants, one ornament, gravel, filter, heater, thermometer, and one mini siphon, will cost $82.
The additional price for maintaining the fish and tank is about $99 annually, including medication if the fish gets sick.

Total Cost for Mid-Grade 5-Gallon Tank

If you prefer to be somewhere in the middle, with an interesting Betta fish, a few quality decorations, and durable tank equipment bought on sale, you can spend between $200-$300 setting up your aquarium.

After that, you’ll spend around another $25 per month on maintenance and general expenses for your Betta, costing a total of $300 annually in maintenance.

Total Cost for High-End 5-Gallon Tank

A high-end 5-gallon tank includes live plants, a top-tier filter, high-quality food, a large siphon, 3 new decorative pieces, and a less common Betta fish. This could cost roughly $614 to put together.

Once your luxurious tank is set up, you’ll need to pay another $550 annually, or $46 per month, plus the cost of hiring someone to care for your fish while on vacation.

Total Cost for Larger Tanks

If you’re looking at larger tanks, such as 10- or 15-gallon options, simply take the price listed above and multiply it accordingly.

For example, if you want a 10-gallon tank, economical setup for your Betta, multiply $82 (cost of 5-gallon economical set up) by 2 for the cost of initial purchases. Then multiply the maintenance cost by the same number ($300 x 2) to add in your annual maintenance cost.

For a 15-gallon tank estimate, multiply by 3, and so on.
