Betta fish are tropical fish, which need a water temperature of 78-80 ℉. So it is recommended to add a small heater to your betta tank in most areas. When you choose a heater, you should take the following factors into account.
Firstly, you should choose a heater with a built-in thermometer. So you can check the water temp in time. Secondly, pay attention to the rate of work, then you can choose one suitable for your tank. And you should know your tank size because the different sizes of tanks will need different heaters. For example, a heater with 100W may be for a 20-30 gallons tank, and a 50W heater can be used for 1-6.5 gallons, which is more suitable for betta fish. By the way, the larger the tanks, the higher the heaters’ working rate. Thirdly, a heater that can regulate the temperature automatically will be perfect.
To keep longer for clean water, an aquarium filter is a must. It is feasible to apply a gentle aquarium filter or one with an adjustable flow because the bettas dislike strong flowing water currents. A small canister filter or sponge filter are ideal options.
Aquarium lights and sunlight
Aquarium lights are not critically necessary for a betta. Bettas prefer a light and dark cycle, like a natural day. However, if there are live aquarium plants in your tank, aquarium lights will be needed.

Besides that, beneficial bacteria may grow on the surface of gravel, which is helpful to decompose the waste. But you should avoid gravel which is made with large rocks because food and waste will be stuck in it.
Plants in tanks can provide shady space for betta fish. And the live aquatic plants can clean the water in tanks and provide a natural environment for bettas. But if you plan to apply fake plants, it is better to choose silk plants, not plastic ones.
