Betta fish are pretty popular among aquarists. You might be surprised to hear that it’s not even necessary to have them inside an aquarium as they can survive in any size container with minimal effort for cleaning and feeding. But as an aquarist when you pet them inside a fish tank, cleanliness is something you can’t skip here, and you have to keep the fish tank neat and clean to ensure your betta fishes survive.

However, when the question is: how often to clean Betta fish tank? The answer is a bit complex as cleaning the Betta fish tank depends on many factors. For instance, You have to consider the total number of fish, the types of decorative items, how clean the water is, etc. The usual time you need to follow revolves around one or two weeks. That means it would be okay to clean your Betta fish tank once a week or two.

The article will let you know the timings to clean a Betta fish tank and how to do that stepwise.

How Often to Clean Betta Fish Tank? : A Complete Guideline

When the aquarium or fish tank has water itself, why does it require cleaning? The answer is simple; the food particles, excretory from fish, and decorative items make the tank filthy after a while.

So, the fish inside won’t get enough oxygen unless you clean the tank.

How Often to Clean Betta Fish Tank

Suppose you have a fish tank with only 2-4 Betta fishes; you will see that there is nearly no dirt even after a week. This is because Betta fishes don’t make the tank dirty too often.

However, if your fish tank is already small and has plenty of Betta fish, you must clean it at least once a week. Otherwise, the environment inside won’t be good enough for the fish to survive.

The cleaning time will vary depending on another situation. For example, the surfaces can get even dirtier if the tank has other fish besides Betta. So, you may need to clean it twice a week even if it seems boring!

Cleanliness doesn’t mean cleaning the tank surface; you should change the water often. You can change the tank water on alternate days because the fishes need clean water to inhale the required oxygen.

Breathing in the old water for quite a long time is impossible. However, if you have a water filter attached to the fish tank, things can get simpler. With this water filter, you won’t have to change the water pretty often.

Experts’ Tip: You must clean the tank if you see growing moss all over the tank. Moss will grow where there is humidity and living things around. You can’t let moss grow on the tank because it’s a parasite and can make your Betta fish sick.

Step 4: Clean the Tank

  • Clean the tank with either soap water or the previously prepared solution (In step 1).
  • Rub the filthy areas with brushes or bristles, but ensure you don’t put too much pressure as it can leave scratches.
