Knowing what makes a good breeding environment for your Betta will make it much easier to find the right setup for your tank. Some key factors will help your Betta pair get lucky and reproduce. It is important to keep these factors in mind when setting up your tank.

– Temperature – Betta fish are tropical fish and will not do well in cooler water. The temperature of your tank should be between 70 – 82°F. If your tank temperature drops below 70°F, you will want to do some quick adjustments to keep it at the right temperature. Use a heater if you are keeping your tank outside or make some adjustments to your tank if you are keeping it inside.

– Humidity – Betta fish are tropical fish, so it is best to keep relative humidity between 40 – 60%. If you keep your tank too dry, the eggs and sperm will stay alive too long, possibly dying before they can complete the process. Keeping your tank too wet, on the other hand, can lead to bacterial growth and destroy the delicate fertilization process.

– Water Conditions – The Water Conditions of your tank should be soft and NOT hard. Hard water is high in minerals that can harm the delicate internal organs of your betta fish.

– Water Flow – The Water Flow in your tank should be moderate. Too little water flow and your eggs and sperm will be washed away too soon.

Offer Water Conditioner for Bettas

While you should try to keep the temperature of your tank between 70-82°F, Bettas do have a natural tendency for higher temperatures. So to keep your Betta pair happy, you can offer your Bettas a water conditioner. This will greatly help lower your tank’s temperature and make it more comfortable for your Betta pair. Conditioners can be found in most pet stores under the name “Betta Safe” or “Betta Boost” and are very affordable. Some online retailers sell conditioners for betta fish, like Bettafish.com/ Conditioner. You can also make your water conditioner by adding 1/2 cup of coffee grounds to your filter. Coffee grounds are high in minerals and will provide your betta fish with much-needed minerals.

Add Soft Sponge for Bettas to Nest on

When it comes to a spawning substrate, soft sponges are the way to go. It is best to get young, fresh sponges that have no odour or have very little odour. Young sponges are less likely to have off-gassing chemicals that may be harmful to your Betta. Sponges are one of the most popular types of substrate (bio-media) for betta fish. The sponge absorbs ammonia from the water so that the eggs and sperm can develop safely in the substrate. Also, sponges provide hiding places for your Betta fish, which helps prevent the stress of being in a crowded tank. Sponges are great for hiding places because they are soft and not too noticeable. If you are not lucky enough to find a soft sponge that is newly washed, you can also put a soft wet towel on the bottom of the tank. The sponge will absorb the water and work nicely as a spawning substrate. 

Install a Bottom Layer in your Tank for Mating

The next factor you will want to keep in mind when creating a conducive environment for Betta spawning is to put a bottom layer in your tank for your Betta pair to spawn on. The substrate you choose for your bottom layer can be almost anything, but we recommend something porous or small enough for your Betta to hide in. A porous bottom layer will help to remove excess dissolved oxygen from the water, which is very important in the process of Betta reproduction. It will also help to keep your water clean from bacteria that can cause issues for your Betta pair. You can also use a porous bottom layer to create a hiding area for your Betta fish. A porous bottom layer will help to remove excess dissolved oxygen from the water, which is very important in the process of Betta reproduction.

Install a Top Layer in your Tank for Mating

Once your tank has been set up, it’s time to set up the top layer. A top layer will help to raise the temperature of your tank and prevent the water from splashing up onto the substrate and ruining it. There are many options for making a top layer, such as an air stone, heater, or filter. Any type of device that creates a flow of water will work great for a top layer. Another important thing to keep in mind when making your top layer is that it needs to be large enough to keep the top layer of your tank at a safe temperature.


The best way to encourage your Betta fish to breed is to create an environment that is conducive to spawning. This can be done by keeping the temperature between 70-82°F, keeping the water clean, oxygen levels low, and keeping the water flow moderate. Next, you will want to provide your Betta pair with a spawning substrate, soft sponge, or small enough to hide in. Finally, the top layer in your tank needs to be kept at a safe temperature.
