Cleaning frequency: Once a month. Observe filter maintenance to avoid decimating the beneficial bacteria living in it. Filters have media that have a large surface area for beneficial bacteria to colonize. You may clean the filter once a month for a 5-gallon tank with one Betta fish.
This allows betta fish to breathe gaseous air from the surface of the water. You will often see betta fish going to the surface to open their mouths and breathe fresh air. Most other fish can only absorb oxygen out of the water, but labyrinth fish like bettas can also absorb it out of the air. This is why betta fish really don’t need aWhen it is, do a 25%-50% water change. Re-test the water 20 minutes later to make sure the ammonia has gone down, if you want. Put water conditioner in before adding new water in to avoid killing bacteria. If its still too high, do another, smaller water change. Dont do 100% water changes while cycling a tank, though!Some people have tank mates, some have filters – some don’t, some people have different size tanks, some have live plants. You will likely only need to do full water changes once a month in a 5-gallon with a betta depending on a few factors like uneaten food, live plants, regular water changes and maintenance. Place a plate on top of your gravel, and pour water on top of the plate to fill your tank. Using a plate with prevent you from displacing the gravel. During this process you’ll want to check for leaks. Don’t fill your tank all the way up, leave about an inch and the top.
My quick answer to this is no – they don’t need one. However, many hobbyists are not able to run a tank filterless nor have the desire to maintain a tank without a filter. Not to mention, many filterless tanks are small and lack other factors that are a must for a Betta, such as a heater.
