Essential Guide to Betta Fish Care: What You Need to Buy


Owning a betta fish is a serious commitment, and it’s crucial to approach it responsibly. Before embarking on this journey, it’s wise to know what you need for a betta fish, such as the necessary supplies ready to make informed decisions from the start of your betta’s life. Being a pet owner entails responsibility for the well-being of the animal, and unfortunately, some novice betta keepers neglect to educate themselves about proper care. Regrettably, this oversight often leads to untimely betta deaths. The good news is that by dedicating just an hour or so to learning, many newcomers could have prevented such outcomes. If you’re reading this, you’re already on the right path to ensuring the proper care of your betta.

Everything You Need to Care for a Betta Fish

Presented below is a fundamental inventory of essential things you need for a betta fish:


Consider the type of tank suitable for your betta—resist the idea of a bowl, as it’s too small and challenging to regulate. Despite the misconception that bettas thrive in compact spaces, they actually need room to swim like any other fish. Bowls pose difficulties in maintaining water conditions and temperature, leading to rapid waste buildup and potential health issues for your betta. Opt for a five-gallon tank with a filter and heater, essential for these tropical fish. This size ensures proper care and ample swimming space. Conveniently, there are fish tank kits available, providing all necessary components in one package, sparing you the hassle of searching for individual items.

Substrate Options

When choosing a substrate for your betta’s tank, consider avoiding glass marbles or large pebbles. These can trap food and waste, potentially harming water conditions unless you’re committed to weekly full water changes. For tanks of 5 gallons or larger, standard-sized aquarium gravel is a better choice. It comes in various colors and textures and is fine enough to prevent food from slipping through, while still allowing for easy cleaning with a gravel vacuum. For the amount, use about a pound of gravel per gallon for larger tanks, but in a 5-gallon tank, simply add enough to cover the tank floor to a depth of at least an inch, based on what looks aesthetically pleasing to you.

Heater and Filter

Your betta, being a tropical fish, likely needs a heater and filter in its tank to thrive. Tropical fish require clean, warm water, so it’s crucial to have a tank large enough, ideally at least 5 gallons, to accommodate reliable heating and filtration systems. Bettas thrive in temperatures between 75 and 80 degrees Fahrenheit. While a heater may not be necessary if the room consistently stays around 75 degrees, such as during summer, remember that water temperatures can drop at night. Therefore, having a heater ensures a stable, suitable environment for your betta, especially when room temperatures fluctuate.

Tank Decorations

Now that your tank and gravel are sorted, turn your attention to decorations. Prioritize your betta’s well-being by choosing only aquarium-safe decorations. Bettas appreciate hiding spots, so any ornament allowing easy access for your betta to swim into is suitable, aiding stress relief and providing an escape from excessive light or environmental factors. Bettas often rest on plant leaves or the tank bottom, so don’t be alarmed if you see this—it’s normal.

While live plants are preferred, plastic ones work well for afternoon siestas. Avoid overcrowding the tank with decorations, ensuring a 5-gallon tank or larger for sufficient swimming space. Beyond that, let your creativity flow, whether it’s creating a natural environment with live plants and driftwood, opting for artificial elements, or even injecting some fun with cartoon characters. Ultimately, as long as your choices align with your betta’s needs, feel free to design the tank to your liking for your enjoyment.

Betta Food

When feeding your betta, base its diet on standard betta pellets or flake food, and consider alternating brands for a varied nutrient intake. Treats like bloodworms or brine shrimp should be given only occasionally, as overfeeding these can lead to health issues, some of which might be fatal. Be mindful of your betta’s small size and only provide what it can eat; excess food should be removed from the tank to maintain cleanliness.

Implementing a feed/fast schedule, where you skip feeding for a day each week, can prevent overfeeding and maintain your fish’s health. Fasting for a day isn’t harmful—it’s harder to starve a fish than overfeed it, and overfeeding poses a greater risk of disease, similar to humans.

Other Essential Items for Your Bette Fish

Add these items to your betta fish care list for a smoother and more enjoyable experience, both for you and your fish:

  • Water Test Kit: Keep an eye on your tank’s water conditions with a test kit. It helps ensure the safety of your betta by measuring pH, ammonia, nitrates, and nitrites.
  • Digital Thermometer: Monitor your tank’s temperature to keep it within the ideal range of 75 to 80 degrees. A digital thermometer is compact and easy to read.
  • Magnetic Algae Scrubber: Make tank cleaning hassle-free with a magnetic algae scrubber. It allows you to remove algae from the tank sides without getting your hands wet. The Mag-Float is a great option; it even floats if accidentally dropped!
  • Water Conditioner: Depending on your water source, consider using a water conditioner in your tank. While it’s best to minimize the use of chemicals, a water conditioner can help remove harmful elements from your fish.
  • Safe Container: Avoid netting your betta if possible, but keep a net on hand for emergencies. If you need to move your betta, use a large cup as a temporary safe container. Choose a cup exclusively for your betta, and remember to cover it.
  • Reference Materials: Despite the wealth of online information, a reference book can be handy for clarifying care issues and understanding your betta’s behavior. It’s a helpful tool, alongside the vast resources on the internet.
