Setting up my new betta fish tank

1) Heater (Optional)
- Is not necessary if you stay in tropical countries.
(I am living in Malaysia, the water temperature is around 25°-28°)
- You will need the heater if you live in 4 season countries.

2) Air pump (Optional)
- Is not necessary to have an air pump if kept only one fish, betta fish can survive without an air pump because they have a special respiratory organ called a labyrinth. Therefore, they just need very small amounts of oyxgen.
- You will need an air pump if you kept more than one fish.

3) Aquarium filter (Optional)
- I don't install filter because I do changes the water regularly. (Once a week, 50% of water every time)
- If you install filter, please make sure the water flow is not too strong because they like calmer waters.

NOTE:
Bad water condition, stress or hungry will lead to Betta fish jump out from the tank.
Healthy Fish: Swimming around.
Unhealthy Fish: Sinking at the bottom or hiding always.
