My betta fish is not active.

There can be numerous reasons behind your betta fish being inactive, of which the primary reasons are poor water conditions and inadequate water parameters.

Poor water conditions and inadequate water parameters result in betta fish losing their appetite and becoming weak.

Weak betta fish will become prone to various diseases and parasites.

They will become sick and less interested in moving, being inactive.

You will usually find them at the bottom of the tank.

More reasons for your betta fish being inactive include inadequate feeding, stress, and a poorly set up tank.

What are the reasons behind my betta fish not active?

All these are the reasons behind your betta fish being inactive:

  1. Your betta fish is living in an inadequate water temperature.
  2. The water quality of your betta fish tank is poor.
  3. Your betta fish is not getting their food adequately.
  4. The tank setup of your betta fish is not proper.
  5. Your betta fish is suffering from illness.
  6. Old age is the factor.

Inadequate water temperature

Inadequate water temperature can make your betta fish inactive.

Too high or too low a water temperature will cause them to feel sluggish and lethargic.

Too warm water temperature lacks dissolved oxygen, which your betta fish require to breathe.

Lack of oxygen will make your betta fish stay at the bottom at one spot to preserve energy.

Cold water results in a dip in your betta fish metabolism.

They take more time to digest their food than regular, which makes them inactive and sluggish.

Poor water conditions

Contaminated water conditions will also make your betta fish inactive.

Dirty water will cause ammonia spikes and oxygen deficiency in the tank, making your betta fish suffer from issues like ammonia burns and gasping for air.

Sick betta will not be interested in moving much and will become inactive.

You must know that even a slight amount of ammonia and nitrite can harm your betta fish.

Inadequate feeding

Food plays a vital role in keeping your betta fish active and healthy.

When you feed your betta fish inadequately and with poor-quality food, they don’t get all the required nutrients for their growth and development.

Poor feeding will make your betta fish sick, and they will become inactive and prone to diseases.

Improper tank setup

Betta fish are freshwater fish and prefer to live in a tank full of live aquatic plants and hiding places.

If your betta tank is not having plenty of live plants, lightning, and hiding places, your betta fish can act lethargic.

Poor lighting can also make your betta fish asleep and inactive.

If your tank is poorly lighted, your betta fish will think it’s not daytime and will feel asleep and become inactive.

Illness

If your betta fish is always inactive, illness can be the reason behind such issues.

Poor water quality, inadequate water parameters, and lack of filtration and aeration can make your betta fish prone to numerous diseases and parasites.

Stress is also the primary cause of illness in your betta fish.

Sick betta fish will lose their appetite and become weak.

Weak fish will be inactive all the time.

Maintaining good water conditions and adequate water parameters will treat most of the issues.

Some illness will require medical attention, so find the issue your betta fish is going through and treat them accordingly.

Old age

Old age can also be the factor behind your betta fish being inactive.

If you have betta fish 2-3 years old, and you notice them being inactive and lazy, old age is the reason.

Check for water conditions and parameters, and if everything is correct, old age is why your fish is inactive.

How to prevent such issues in my betta fish?

Ensure all these things to prevent your betta fish from such issues:

  1. Provide your betta fish with good water conditions

  4. Feed your betta fish adequately with high-quality food.
  5. Keep your betta fish in a proper setup tank.

Good water conditions

Providing your betta fish with good water conditions will eliminate most of the causes behind their inactiveness.

To ensure good water conditions, perform a weekly water change of at least 30% of your betta fish tank.

Make sure to treat the tap water when performing a water change with a water conditioner to dechlorinate it. 

We recommend using the API water conditioner to treat the water.

The API water conditioner will help you eliminate chlorine, chloramine, nitrite, ammonia, and heavy metals from the water.

Adequate and stable water parameters

Adequate and stable water parameters will prevent your betta fish from such issues.

Maintain the water temperature between 75-80 °F.

Provide the water pH level between 6.5-8.

Ensure the water TDS level is between 250-280.

With adequate water parameters, it is also necessary to maintain stable water temperature.

Consider adding a heater to your betta fish tank to ensure stable water temperature.

Also, add a digital thermometer to keep a regular check on the water temperature of your betta fish tank.

Provide stress-free environment

Stressed fish will become inactive and remain at the downside of the tank most of the time.

Providing your betta fish with a stress-free environment will prevent your betta fish with such issues.

Ensure good water conditions and adequate and stable water parameters, and avoid overcrowding and overfeeding your betta fish to prevent stress.

Consider keeping your betta fish in at least a 5-gallon tank instead of a bowl.

Feed adequately and high-quality food.

Food plays a very vital role in keeping your betta fish healthy and ensuring their longer lifespan.

Bettas are carnivore fish and require high protein meat-based food daily.

Feed your betta fish with betta pellets, brine shrimp, mosquito larvae, bloodworms, and tubifex worms.

Bettas’ stomachs are the same as the size of their eyes, and they can’t eat much at a time.

Feed them 2-3 pellets at a time for 1-2 times a day to avoid overfeeding and ensure adequate feeding.
