Can Danios Live with Bettas?

A passionate fish pet owner would want to keep different fish species in a tank.

Who wouldn’t want to keep their home aquarium beautiful?

However, keeping many fish varieties together takes a lot of work.

While some of the fish types are compatible, others are enemies.

In this case, can Danios live with Bettas? You may come across divisive opinions, as some are against it, while others recommend it.

It’s only fair to know about these species to understand their nature and determine whether to keep them together.

In this post, we’ll give a guide on these fish species and factors to consider if one has to maintain a community tank with these fish.

Understanding Danios

Danios are peaceful and socially active fish that dwell in freshwater.

It belongs to the Cyprinidae family, consisting of different types and appearances.

The fish is a native of Southeast Asia and is omnivorous.

It has over twenty-seven species, and some of the common ones are:

  • Giant Danios.
  • Zebra Danios.
  • Celestial Pearl Danios.
  • Rosy Danios.
  • Dwarf Spotted Danios.

They are small-sized fish where the female species are larger than their male counterpart.

Its ideal water temperature is between 64°F and 79°F but is adjustable to most of the water conditions.

It also prefers a neutral pH level of 6.

0 to 8.


When it comes to tank size, the ideal size is ten gallons for six to twelve fish.

Increase the size if the fish number is more.

Danios are not bottom dwellers, so the substrate is not required.

However, we suggest using soft and fine sediment to replicate its natural habitat.

Understanding Bettas

Bettas are some of the most attractive fish species but are pretty feisty.

It’s also popularly known as ‘Siamese fighting fish’ as they are used for betting, which is closely similar to cockfights.

This freshwater critter has prominent tailfins and a relatively small body, making them a unique-looking fish.

The fish is known for its dominant nature, especially male Bettas.

In fact, it’s advisable to keep one male Betta with two or three females.

These species may be aggressive but easy to care.

Since it’s a small fish, a five-gallon tank size will suffice.

However, we recommend getting larger capacity tanks as they are active swimmers, especially if there are more fish.

Its ideal water temperature is between 74 °F and 81°F, and it feeds mainly on insects, larvae, and bloodworms.

Bettas are a native of Southeast Asia and are domesticated widely in this region.

Due to its popularity, they are also largely imported.

Can Danios Live with Bettas?

Now that you have understood the characteristics of both species let’s find out whether they can make good tank partners.

Bettas are notoriously known for being the worst tankmates.

So, it’s given most species don’t make the cut to live with this feisty critter.

In this case, Danios are docile but can be pretty aggressive, especially to long-finned and slow-moving fish.

We only recommend keeping these fish species together if certain factors are met.

Are you wondering why we are against keeping these fish together? Here are some of the reasons:

  • Danios and Bettas require different water temperatures. It would not be easy to keep them in the same water condition unless some adjustment is made that is suitable for them.
  • Bettas are active swimmers, but Danios are faster. It can threaten slow-moving Betta, leading to a stressful environment.
  • Fin nipping behavior is more prominent in Danios, especially when they are in a group. Since Bettas are slower and have long tailfins, they are likely to get bullied.
  • Danios are more social than Bettas. They stay in groups and will harass Bettas, who mainly exhibit solitary behavior.
  • Bettas are territorial, and socially active Danios may intrude on their area. It will lead to fights among these species.

Check online forums, and many will not recommend keeping these species together.

People who kept them together have to consider various factors.

You must consider tank size, water temperature, diet, and more.

Furthermore, constant monitoring is required to observe these fish and identify any weird behavior.

Compatibility Consideration

Keeping these fish species together calls for massive responsibilities.

They will make your home aquarium look better as both are aesthetically pleasing.

However, both have different natures and characteristics which prevent them from coexisting peacefully.

The good news is that there are some factors that you can consider in order for these species to cohabitate without harming each other.

Some of the factors you need to consider before you plan to keep these species together in a tank:

  • While keeping these fish in a tank, ensure Danios are put first. Bettas are territorial, and keeping them first will allow them to dominate the area, causing aggression from both ends.
  • Female Bettas are less aggressive than male ones. If you’re not planning to breed, you can keep only the female ones with Danios. .
  • Danios has different types. One of the variants that’s compatible with Bettas is Zebra Danios. This type can tolerate any water temperature. So, we recommend getting this variant to keep with Bettas.

These factors will ease the task of maintaining a community tank of these species together.

If you’re ready to shoulder the responsibility, then proceed.

However, closely monitor them to observe their behavior.

If there is constant bullying or attack, it would be better to maintain a separate tank.


All in all, these species don’t make an ideal tank partner.

We suggest looking for alternatives that are compatible with these fish.

Both are unique-looking fish, and many would love to place them together.

However, keeping them together in a tank is likely to create a hostile environment.

Even the water temperature requirement is different for both species.

Most importantly, both may exhibit aggressive behavior if the habitat doesn’t align with their natural environment.

If you’re up for it, consider the factors we have mentioned above.

It will help you with the dos and don’ts.

Individually, they are easy to care for but can be hard to look after when together.
