Hi, I'm Matt! I've been obsessed with fishkeeping for over 15 years now and created this site to share my knowledge with others.

Zebra Loach is a small, peaceful freshwater loach that beginner-level aquarists can’t stop admiring. With the beautiful stripes all over their bodies, it’s easy to see why Zebras have quickly become everybody’s favorite pet fish of the Loach family.

While many aquarists have turned to Zebra Loaches to control the snail population, they are just as captivating as pet fish. They are a low-maintenance species, and caring for them will be a breeze if you understand what they want at home.

The fish’s remarkably stripped body pattern has earned it other beautiful names like the Striped Loach, Thin Line Loach, Candy Stripe Loach, and Candy Loach.

And regardless of how you view them, Zebra Loaches will be a wholesome addition to your aquarium only if you understand their requirements.

This post is specifically dedicated to Zebra Loach care. And in the forthcoming paragraphs, we will exhaustively discuss the fish’s crucial living aspects like lifespan, appearance, tank size, diet, behavior, tank mates, breeding, and a lot more.

Species Overview

Zebra Loaches are a unique freshwater fish that make an excellent choice for newbie aquarists.

As the name suggests, Zebra Loach boasts a beautiful, striped body pattern that also gives it the scientific name, Botia striata, the species name in this case denoting the multiple, visible strips on their bodies.  

These fish are endemic to western India. And just like most Loach fish, they reside in slow-moving rivers and streams, where they spend much of their time minding their own business.

In recent years, multiple factors have contributed to the massive decline of Zebra Loach’s wild population, almost restricting their presence to specific regions around the world.

Today, you will find their largest population in western India, and not any other region again, unlike in the past, where they had a strong presence in different parts of the globe.

Still, that hasn’t stopped aquarists from flexing their fishkeeping abilities using a species best known for its beauty and peaceful coexistence with most freshwater fish.

As usual, we encourage aquarists to be vigilant when purchasing their favorite Zebra Loach just to be sure they are getting the right species from a reputable seller. That way, it will also be easier to save the fish’s already dwindling wild population.

So, how long do Zebra Loaches live?

You will be delighted to know that Zebra Loaches boast a solid lifespan of up to 15 years despite their small body sizes. 

The standard lifespan of a fully mature Loach can be anything from 10-15 years, but as usual, a lot has to go into their care to help them reach the larger end of the spectrum.

If you are one to build a lasting bond with your favorite pet fish, there you go.


The thought of Zebra Loaches getting named after the gorgeous black and white striped mammal says it all.

And in all honesty, Zebra Loaches’ all stunning appearance is probably the only reason you will want to keep them at home. They are just exquisite, and many aquarists can’t get enough of their unparalleled beauty.

When you first see Zebra Loaches, you will be instantly attracted to the beautifully alternating striped patterns around their bodies. These stripes appear in different color variations, with a dark, yellowish-brown hue always the most dominant.

On top of that, Zebra Loaches have semi-translucent fins that may or may not be stripped. They have wide ventral and pectoral fins, with forked caudal fins and a distinct dorsal fin resembling a fan.

Regarding the general body appearance, Zebra Loaches have the typical loach-shaped bodies, with their prominent heads and mouths slanting downwards. Their bodies appear streamlined from the head but taper down towards the dorsal fin. 


A typical Zebra Loach will measure about 2-4 inches in maturity. However, this depends on multiple factors such as quality care, tank water conditions, and genetics.

Such body lengths portray Zebra Loaches as small fish but don’t assume anything when setting up their habitat. Still, these fish deserve a significant tank size with enough swimming space and suitable companions.

Zebra Loach Care

Zebra Loach is every aquarist’s dream pet fish, and that’s down to their manageable care requirements. The fact we recommend these fish to newbie aquarists and anyone looking to experiment with a Loach variety says it all.

However, we don’t mean you should neglect the fish’s critical needs in captivity or keep them in a substandard environment.

In the next section, we highlight what’s involved in proper Zebra Loach care at home;

Tank Size

Let’s start with the tank size.

Unfortunately, many aquarists see the 2-inch long Zebra Loaches and hastily conclude that they will thrive in small tanks. Of course, we agree with many fish keepers that these are small freshwater fish. However, we discard the notion that Zebra Loaches can flourish in a small tank or bowl.  

From our experience, the ideal tank size for Zebra Loaches should have a 30-gallon capacity. Look, they might be a small-sized, bottom-dwelling species, but Zebra Loaches thrive in small groups.

For the best experience, we recommend a minimum of 5 fish in captivity at any given time.

Water Parameters

Every aquarist agrees that consistency is the key to keeping happy Zebra Loaches at home. While their resilience readily makes them attractive to many fish lovers, Zebra Loaches will have their best life in a natural-looking environment with the best possible tank water conditions and ideal tank mates.

The suitable water parameters are best maintained as highlighted below;

  • Water Temperature: 73°F-79°F
  • Water Hardness: 2-10 dKH
  • pH Levels: 6-7.5

As an additional care guideline, make sure to cycle and change at least 25% of the tank water every week. This is the secret to creating an amazing habitat that promotes the health and well-being of your Zebra Loaches.

A robust filtration system and reliable aquarium testing kit are other essential must-haves to help maintain the tank water in the best possible state.

What to Put in Their Tank?

So, what would you want your pet fish’s ideal habitat to look like? Well, that would depend on the specific species you keep at home.

If it’s Zebra Loaches, everything will revolve around mimicking the natural environment. And it’s only by first understanding the fish’s diet, behavior, and activity levels that you will know what matters most to them in captivity.

Zebra Loaches are such a playful character and will spend a huge chunk of their time towards the bottom of the aquarium. So, they prefer a soft sandy substrate.

Besides, they need a comfortable substrate to eliminate the risks of suffering bodily injuries from deep cuts. That’s almost impossible to replicate with gravel or other rough surfaces.

Proper aeration is important to Zebra Loaches, so you must include enough types of natural plants in the aquarium. Plants also give them additional food choices to supplement their routine diet.

Regarding the lighting conditions, just keep it as dim as possible. They might be more active during the day, but Zebra Loaches enjoy more subdued lighting conditions.

We will never stop reminding aquarists to limit the decorative elements inside the tank. As tempting as it may be, overcrowding Zebra Loach’s habitat doesn’t necessarily translate to more comfort.

Because at the end of the day, these fish will need enough swimming space right in the middle of the aquarium. And you can only achieve that by limiting the number of decorations inside the tank.

Common Diseases

With their hardy nature, one would easily assume Zebra Loaches are automatically immune to freshwater fish diseases. But that’s far from the truth.

While many aquarists marvel at the resilience of the captive-bred species, Zebra Loaches can get sick from common diseases affecting other freshwater fish, with Ich as the most troublesome of all. 

Ich is a highly contagious parasitic infection that many aquarists might have heard about from time to time. While it’s not the most severe freshwater disease out there, it can be devastating if the initial symptoms go unnoticed. 

Usually, the first step to controlling Ich spread is to isolate all the infected species. Later, you can increase the water temperatures to a suitable level or purchase the right antibiotics to treat the infection. If you can’t seem to make any progress at all, seek an expert device.

Other conditions like skin flukes, swim bladder disease, fungal and bacterial infections may also affect the Zebra Loaches at home but are rarely troublesome.  

The increased vulnerability to bodily injuries from small fights and rough substrate readily predisposes Zebra Loaches to serious health concerns. So, that’s a key area you must pay attention to if you keep these fish at home.

What Do Zebra Loaches Eat?

Zebra Loaches are best described as natural omnivores that eat different foods inside the tank. Their typical diet is just as diverse as their tank mates, and you can start by feeding them on sinking catfish pellets without making things quite complicated.

To help them obtain essential nutrients from ordinary fish food, introduce them to vegetables like spinach, cucumbers, lettuce, and zucchini.

On top of that, Zebra Loaches are happy to feed on protein-rich foods like brine shrimp, daphnia, mosquito larvae, and bloodworms.

To complete their diverse diet in captivity, you can also introduce them to algae and other plant-based foods to satisfy their dietary needs. But don’t restrict them to algae wafers alone because that’s not entirely a Loach thing.  

Behavior & Temperament

Zebra Loach’s temperament is exactly what you need from a favorite pet fish; peaceful and energetic yet so adorable. If you don’t spot them snacking on their favorite food in captivity, they will be exploring the soft sand substrate right at the bottom of the tank.

As far as Zebra Loaches’ activity level goes. It can go from bad to worse and again to better in just a few minutes. Calling them unpredictable is an understatement. 

Or let’s say, Zebra Loaches are not one of those dull species that won’t add any value to your already boring aquarium.

Many people keep them at home to liven up the interior home décor, and they truly understand the assignment.

Sometimes, you will spot them hiding in one location like a motionless fish. But in the next moment, they could be roaming freely inside the tank, sending the vibes of a priceless freshwater fish that’s perfect as a favorite pet.

Again, it won’t be long before they return to their favorite hiding spot. So, that’s the typical routine of a mature Zebra Loach. From partially active to inactive and slightly active again as the cycle continues.

Sometimes, the atmosphere can get tense if you keep less than five fish together, where most species will be quick to show their feisty personality. But it’s no call for concern because Zebra Loaches are not known for any aggressive tendencies.  

Zebra Loach Tank Mates

As we’ve stressed before, the easiest way to maintain a thriving Zebra Loach community is to keep multiple species in the same aquarium.

It gets even more interesting if you have five species of the same type, casually exploring the tank as they display the majestic beauty of an invaluable pet fish.  

Outside their family, you can settle for any of the following fishes as the ideal tank mate for the beautiful Zebra Loaches;


Don’t stress over Zebra Loach breeding at home because nobody has done it successfully just yet. Look, we are not saying you shouldn’t consider the Zebra Loaches as an ideal aquarium fish, but if you want to keep them peacefully at home, you better forget about breeding them for a second.  

Professional breeders have done it before, but they rely on hormones and other robust equipment to pull it off, albeit with some difficulties.

Zebra Loach breeding almost certainly ends in frustration, and the quicker you accept that, the better the fishkeeping adventure.

From our experience with many Loach fish, there’s nothing more to add to Zebra Loach breeding at the moment. At best, it can only increase the stress levels inside the tank, making your fish more vulnerable to new infections.

That’s why we strongly discourage aquarists from even thinking about it. After all, you can still create the perfect aquarium with your beautiful Zebra Loaches as the center of attraction without breeding.

Of course, we won’t hesitate to keep you posted when aquarists make any progress in this regard.
