Betta Fish Basics

Betta Fish are one of the most popular aquarium fish species available. Here’s a QUICK BETTA GUIDE on how to care and provide a good home for your Betta!


• The minimum tank size for a single standard betta is 5 Gallons. If you have a Giant Betta, it’ll be 15 Gallons, minimum.

• It is incredibly important to provide a good swimming and flaring space for your fishy friend.

• Despite popular beliefs, they do require adequate swimming space.


• A cycled tank is essential for a thriving fish and aquarium.

• Our aquatic pets need a cycled environment in order to thrive. Check out How To Cycle An Aquarium here.

• Betta Fish love Blackwater Tanks. Adding botanicals into your tank will lower the water’s pH level. However, if you’re not a fan of blackwater tanks, it is completely fine to keep them in a clear water tank.

• The recommended water parameters are as follows : Ammonia : 0, Nitrites : 0, Nitrates : less than 20 ppm, Ph : 6.0 – 7.0 , GH : 3 – 4 (50.0 – 66.7 ppm) , KH 3 – 5 (53.6 – 89.4 ppm).


• Betta fish are tropical fish.

• Keeping them in cool temperatures will affect their immune system; making them more susceptible to diseases.

• The recommended temperature for a betta is 78.8 – 86.0 °F .

• If you live in a cool area, aquarium heaters are a life saver! Check out Heaters here.


• If you have a Walstad Tank, you can skip this tank.

• But let’s be real, we’ve just started and most of us don’t have a walstad tank!

• Filtration is important to maintain good water quality in our tanks.

• It is also a home for our good beneficial bacteria! (Refer How to Cycle an Aquarium.)

• Betta fish appreciate a slow to moderate water flow, as long as it is not overpowering.

• Filter size depends on your tank size.

• Check out the array of filters here.


• Lights are great to help regulate your betta’s circadian rhythm.

• That way, they’re able to know when it’s daytime or night time (and even feeding time.)

• If you have a planted tank, lights are essential for plant growth.


• The tank is your canvas and you are the artist!

• Betta fish appreciate ornaments, plants (live or fake) and caves for them to rest on and explore!

• Substrate-wise, gravel, sand or soil is fine. If you’d like to have a planted tank, having a soil substrate will open up a lot of plant options for your tank.


• Lucky for us, betta pellets are readily available, making feeding time a piece of cake!

• Feed them good quality, carnivorous pellets.

• Remember to not overfeed your betta fish. 3 – 5 pellets per day is sufficient. For fine grained pellets, a little pinch is enough.

• Besides that, frozen food such as frozen bloodworms and frozen brine shrimps can be given as occasional treats.

• If you’re feeling adventurous, live food such as baby brine shrimps, daphnia, and microworms will encourage your betta to hunt, making an enjoyable feeding time for you and your betta fish!


• We recommend a 30 – 70 % of waterchange once per week for a cycled aquarium.

• Please note that the percentage of waterchange does not matter once your tank and filter are cycled. However, we do not recommend anything less than 30%.

• A majority of good beneficial bacteria lives inside your filter, filter media, sponge and substrate; not in the water column.

• So, performing a waterchange more than 70% will not harm your tank’s cycle.

• Filters and filter media need to be submerged inside dechlorinated or aquarium water at all times.

• Good aquarium beneficial bacteria are aquatics creatures.

• Chlorine will kill these good bacteria.

Looks like you’re all set! We wish you the best of luck with your Betta Fish!
