Can Kuhli Loaches Live with Bettas?

Bettas are famously known for being a terrible tank partner due to their aggressive behavior.

Most of the fish species don’t mingle well with this critter.

So, can Kuhli Loaches live with Bettas? Surprisingly, they can cohabitate.

In fact, Kuhli is one of the few species that can stay peacefully with this feisty Betta in a tank.

Find out more about these species below.

As a fish pet owner, it’s only fair to understand the nature and characteristics of these fish.

It will help you understand these species better and arrange their habitat accordingly.

You can maintain a community tank with these fish, but you also need to meet some factors.

Learn below.

Understanding Kuhli Loaches

Kuhli Loach is a small freshwater fish that looks like an eel.

In fact, it’s also referred to as eel loach for its slender body like a snake.

This nocturnal critter is a native of Java Island, Indonesia, and is part of the Cobitidae family.

This snake-like creature is famous for home aquariums due to its unique pattern and features.

They have multi-colored pattern and has over fifteen dark stripes.

There are different variants of this fish, and one of the popular types is Black Kuhli Loach.

Appearance wise, it looks a bit different from the regular ones.

When it comes to tank size, the ideal capacity is fifteen gallons.

You can increase the tank capacity if the population is larger.

The ideal water temperature for this fish to thrive is between 73°F to 86°F.

This fish is calm and quite reclusive but gets active at dusk.

Once the sun sets, they will start looking for food consisting mainly of water fleas and bloodworms.

Understanding Bettas

Bettas are also small freshwater fish that are well-known for their fighting spirit.

In fact, it’s famously called the ‘Siamese fighting fish.


The fish is also the national aquatic animal of Thailand.

It’s native to Southeast Asia and found abundantly in this region.

Due to its extravagant look, this fish has become widely popular among aquarists.

It is widely imported for home aquariums.

Despite its popularity, these fish are pretty territorial, showing aggressive behavior.

Hence, this trait makes them poor tank partners.

Only a few fish species can live with Bettas peacefully.

The water temperature requirement for this fish is between 74 °F and 81°F.

Since it’s a small-sized fish, a five-gallon tank will be great.

However, it would be better to get a larger tank for them to move freely as they are active swimmers.

Can Kuhli Loaches Live with Bettas?

Kuhli Loaches are one of the few species that can live with Bettas.

They are known to fend for themselves due to their reclusive nature.

They can hide well and protect themselves from their enemies.

In this case, Kuhli can keep up with the Bettas.

Another important factor is this eel loach doesn’t nip fins.

Since Bettas have extraordinary tailfin, it’s often a threat, especially from fin nippers.

However, you can cast your worry aside in this case, as Kuhli Loaches are not fin nippers.

Overall, expect a peaceful living environment, given that you have met their natural habitat conditions.

Often, there is aggression or bullying among these critters due to unsuitable living habitats like poor water quality, limited space, or inappropriate water temperature.

Especially if you’re maintaining a community tank, these are essential factors that you need to consider.

In this case, consider these species’ water temperature, tank size, and diet.

The ideal water temperature for both fish is the same, which is good news.

Ask an experienced aquarist how challenging it is to maintain an ideal water temperature for different species.

Even the tank size requirement and food are somewhat the same.

The only factor you need to pay heed to is the male and female Betta ratio.

There should be one male Betta to two or three female Bettas.

Male Bettas are dominant and very possessive.

It leads to aggression and fights with other fish.

Their female counterparts are less aggressive and connect better with other species.

Compatibility Consideration

Bettas and Kuhli Loaches are a match made in heaven.

One is feisty, while the other is docile.

Despite Kuhli’s calm nature, this fish can protect itself from bullying.

Moreover, they are not super active and love to stay in a specific place.

In comparison, Bettas are highly dominant.

They are territorial and get aggressive if others intrude on their space.

In fact, they even fight among its kind.

While contrast behavior or nature often leads to incompatibility.

However, in this case, it’s the opposite.

Both have different traits, yet these make them suitable for each other.

It’s intriguing, but it’s like hitting a jackpot for aquarists.

Imagine two aesthetically pleasing critters in your home aquarium coexisting peacefully.

It’s a dream for many passionate aquarists.

However, we would also like to bring up factors like tank size, water quality, and temperature, which play a crucial role.

If there is limited space or poor quality, these fish may fight, especially Bettas.

Hence, much of the peaceful living environment depends on how you take care of the aquarium.

Being an aquarist is a difficult task.

These fish may be easy to care for, but one needs to monitor them regularly and see if they exhibit weird behaviors.

Once you identify it, separate them or maintain a different tank for both species.

Although fights are less likely to occur between these two critters, you still need to be vigilant.


Go ahead if you plan to keep these fish together in a tank.

They may have contrasting characteristics but are suitable for each other.

It’s not the same for most fish species, but the situation is quite the opposite in this case.

Bettas, especially the male ones, are quite aggressive and territorial.

They even fight among their kind.

In comparison, Kuhli Loaches simply mind their business.

It’s one of few species that can defend or protect themselves from Bettas.

These two make an ideal tankmate, and we highly recommend this pair.
