Generally, people can’t decide the proper size of tanks for their betta fries. Some experts think that if the tank’s size is small, you can easily monitor everything.

That’s why you need to neutralize the tap water before adding it to the tank.

How Can You Dechlorinate Water?

Dechlorination is quite easy. You can simply boil the tap water before adding it to the betta fry’s tank. Boil it for at least 25 minutes to remove all chlorine. Don’t forget to cool it down before adding it to betta’s tank.

Further, you can use a UV sterilizer. Carbon filters can also be an easy option to dechlorinate water for the tank. Again, you can put a spoon of ascorbic acid into each gallon of water.

If you don’t want such trouble, you can just let the water set. Put the tank of water under direct exposure to sunlight for 20 hours. By following any of the above-mentioned ways, you can add dechlorinated water to the betta fry’s tank.

Is Distilled Water Okay For Betta Fries?

The answer is a big NO. You mustn’t put distilled water in the tank of betta fries. It doesn’t have any minerals or nutrients which is important for the survival of betta fries.

Also, the pH of distilled water is controlled. So, distilled water can’t be okay whereas the slightest change of pH swing can be deadly for betta fries.

Décor And Plants

We perhaps don’t know that bettas love to hide under plants and decors. You need to ensure that these decors or plants are not harmful or unsafe to betta fries.

There are plenty of options for decors and plants. For example

  1. Lava rocks,
  2. Marimo Moss Balls,
  3. Sinking Ceramic Betta Log,
  4. Cattapa Leaf
  5. Betta Leaf Hammock
  6. Driftwood,
  7. Silk Aquarium Plants
  8. Floating Plants or Aquarium Plants

A nice decoration in the tank helps betta fries be stimulated. Also, this makes them active and improves their immunity. Make sure that betta fries have enough place to swim in the tank.


It’s better to place a filter in the setup of betta’s tank. Just like other fish or plants, betta fries release ammonia into the water. To deal with ammonia, we need bacteria that we can get through filtration.

Although betta fries can survive without a filter, filtration helps keep water safe for betta fries. There are varieties of suitable filters for the betta tank, such as – sponge filter, corner filter, internal power filter, etc.

For a 10 gallon betta tank, I’ll suggest a good Hang-On-Back Filter. Hang On Back filters don’t take up any space inside the aquarium and they are perfect for small to moderate sized tanks. My recommendation will be the Penguin model from Marineland.


Lighting is equally important as warmth in a tank for betta fries. When you set up a tank for betta fries, try to place it close to a window.

In this way, betta fries can easily get natural sunlight. But, you shouldn’t keep them under direct sunlight for a long time. This puts risks of UV radiation which can hurt betta fry’s eyes.

Otherwise, you need to arrange lighting in the tank artificially. You can prefer plain white LED light or an aquarium light.

Don’t forget to turn off the light at night. This helps create a schedule for betta’s sleeping pattern. After all, they’re tropical fish.

Fry Tank Maintenance

It’s really beautiful to nurture betta fries and see them growing. But you need to care and remember some tips for fry tank.

  • Many people ask if they need to cycle a fry tank. Since betta fries release waste as ammonia, only bacteria can remove this. Cycling gives such bacteria a good time before adding breeding betta. If you can’t cycle before adding betta into the tank, you can do fish-in cycling.
  • The water change of a fry tank depends on its water condition. If you have a filter in the tank, you need not change water frequently. Otherwise, you can change 10% of the water in two days. It helps fasten fry’s growth.
  • You need to concern about the tank’s cleanliness. Usually, a small tank gets dirty fast. When you clean the fry tank, make sure to wash the rocks, décor, plants too.

In total, take care of betta fries and make proper maintenance of the tank. Thus, your fries will grow into a healthy, colorful betta.
