Betta Fish Filtration, Heaters, and Other Considerations
In this lesson, we are going to discuss other items your betta fish will need besides the aquarium itself. If you are going to only keep one betta fish, you really do not need any filtration. You will still need to change the water from time to time.
However if you are going to add tank mates, you will need some additional filtration. I would suggest that you get a filter that hangs on the back of your aquarium. You will need to purchase a lid or top for your betta’s home. Betta fish can and do try to jump from time to time if they are startled or frightened so you need to keep a roof over their heads so to speak.
You will also need some sort of gravel (substrate). I would also recommend that you purchase a small aquarium heater no matter where you live. The real purpose of a heater is to not only keep the betta fish’s water warm, but it keeps the water at a constant temperature. The room where your betta stays might be 75 during the day, but at night the room temperature might drop to 65. Having the betta’s water temperature cycle up and down will both stress the fish and cause it to get sick over time.
Other items you can buy are some decorations. I would recommend that you only use gravel and decorations that come from an aquarium store, or a fish department in a pet store, as they are not toxic to your fish.
