How to prevent your betta fish from jumping out of the tank?

There are a variety of reasons why bettas may jump out of their tanks. Here are the main ones:

Aquarium lid or screen tops for bettas aquarium

Because betta fish is a jumper, you will need a tank lid unless the top of the tank is a few inches above the surface of the water. 

Do not block the surface of the water as it absorbs oxygen on the surface of the water.Make sure to use only lids with air holes.

Glass covers tend to be the most durable, efficient & versatile covers. They are easy to clean, and are more durable than plastic.

Floating objects in bettas aquarium

Placing floating objects on the surface of the water in an aquarium is a good idea, but they are not reliable in their ability to completely stop a betta from making such a big jump. Things floating on the surface will only get in the way.

Floating objects that can be used in bettas tank:

  • Floating plants
  • Floating logs
  • Natural driftwoods
  • Toys 

Provide bettas bigger and spacious tanks

Betta fish should not be kept in small and compact containers, but a tank with adjustable temperature and water chemistry will provide them with a comfortable and stimulating home. 

When their environment isn’t suitable for fish, betta fish can jump out of an uncovered tank or bowl.

It is very important to keep bettas in a spacious tank without overcrowding their tank. An overcrowded and compact tank is majorly responsible for such behavior.

The minimum tank size is three gallons and additional tank size for each fully grown bettas is one gallons.The ideal tank size for single male or female bettas is five gallons.

Avoid stressors in bettas tank

Betta fish get nervous or easily frightened due to aquarium changes, incompatible tankmates, and environmental factors can all contribute to the stress of aquarium fish. 

Some bettas may find it difficult to adjust to a new tank.It is very important to choose their tank mates wisely and remove anything which is triggering stress. 

Always acclimatize bettas properly before introducing them to a new tank to avoid jumping tendencies.

Maintaining water temperature and pristine condition in bettas tank

Bettas can clear an open top aquarium if the water level is high enough.

Betta fish tend to jump out of an aquarium that has poor water quality or a temperature that is too warm in general.

The ideal temperature for bettas is between 78-80°F. Always maintain water parameters in the bettas tank to avoid such mishaps.

Maintaining water pH in bettas tank

If the water in your tank becomes too acidic, it could have a negative effect on your betta. Betta fish works best when kept at a neutral pH of 7.0-7.5. They are tolerant of slightly acidic water as low as 6.5.If this is not maintained, chances of bettas leaping out of their tank will be high.

Add compatible tank mates in bettas tank

Depending on the size of your aquarium, some of the best betta aquarium companions are:

  • Mystery snails.
  • Ghost shrimp.
  • Moss balls.
  • African dwarf frogs.
  • Small Corydoras species.
  • Some types of tetras.
  • Harlequin rasboras.
  • Feeder guppies.

Maintain bettas sleep cycle

Just like you and I, your betta has a natural sleep cycle that he needs to follow. If he does not follow his sleep cycle, he will become restless and frustrated. 

If the tank is not managed properly, the fish will begin to become confused as to when they should be resting and when they should be awake. This could lead to them jumping out of the tank accidentally.

Switch off aquarium lights in the night and switch it on during day time to maintain their sleep cycle, as this will help them to differentiate between day and night time.

Maintain betta fish tank properly

One of the most important things you can do to keep your tank healthy is to keep it clean. There are many different ways you can do this. Make sure to do water changes and vacuum the gravel regularly to remove any decaying matter.

Make sure the light effects are right in bettas tank

If you’re not regularly providing your betta with light, you should start. Believe it or not, properly lighting your bettas tank can help to keep their circadian rhythm healthy. 

Make sure you give your betta at least 8 hours of uninterrupted rest each day so he can recover from his activities.

Not providing the right lighting might stress your bettas and can trigger them to jump out of their tank.


Two to three inches above the water is the average height a betta can reach.

Bettas are excellent jumpers and may leave open aquariums or bowls when environmental conditions are not suitable.

Betta fish need plenty of space to swim and hide. Make sure that your aquarium is big enough for the fish you are getting. Betta should be stored in a tank with a minimum of five gallons, but ten gallons is even better.

Bettas tend to jump in an attempt to escape an aquarium with poor water and excessive temperatures. 

Checking the aquarium water temperature with a decent thermometer is a good way to prevent betta fish from jumping.  

Regular water changes are required as part of proper maintenance of the betta tank.

If you want to keep a betta sorority, you should consider covering that aquarium.

Even if you haven’t seen a betta jump, it doesn’t mean that a betta fish can’t jump.They are very much capable of jumping out of their tank.

Betta fish is a great jumper. Unless the top of the tank is a few inches above the surface of the water, you will need a tank lid.

Covering your betta’s tank will help keep him safe and comfortable. It should be a priority, but you should also make sure there is no other reason for your betta to jump out.
