We will cover topics such as diet, tank size, tank mates, and more. By the end of this guide, you will be an expert on gold barb care!

Species overview

The gold barb (Pethia conchonius) is a tropical freshwater fish that’s native to South Asia. They’re most commonly found in the Indian subcontinent, as well as parts of Pakistan, Nepal, and Bangladesh.

They prefer habitats with slow-moving water and plenty of vegetation. This could be in the form of a river, stream, or even a lake. As long as there’s plenty of plant life for them to hide in and plenty of food for them to eat, gold barbs will be happy.

Gold barbs are very peaceful fish and do well in community tanks. They’re also one of the few fish that can tolerate cold water, which makes them a good choice for those who live in cooler climates.


Gold barb

The Gold Barb is a very popular freshwater fish and it’s easy to see why. They’re very beautiful fish that stand out in any tank.

As their name implies, these fish are mostly gold in color. The gold can vary in intensity and sometimes has a slight greenish hue. There is a black horizontal stripe that runs along their body, starting at the gill plate and ending right before their tail fin.

This stripe is usually broken up into a few different sections. The first section is the thickest and is right behind the gill plate. The next section is a bit thinner and extends to the middle of the fish. The last section is the thinnest and extends to the end of the fish.

The fins on a Gold Barb are all quite small. The dorsal fin is the biggest, but it’s still relatively short. The anal fin is a bit smaller and the caudal and pectoral fins are quite tiny.

The body of the Gold Barb is long, thin, and torpedo-shaped. This gives them a lot of speed and agility in the water.


The lifespan of a gold barb is around 5 to 8 years, although some have been known to live for up to 10 years.

As with all fish, there are a number of factors that can impact their lifespan. The quality of their environment is probably the most important one.

If they’re kept in a tank with poor water quality or not enough space, their lifespan will be significantly shorter.


The maximum size of a Gold Barb is about 2 inches in length when fully grown. It’s not uncommon for these fish to stop growing at 1 inch depending on their level of care and genetic factors.


Tank Size

The minimum tank size for gold barbs is 20 gallons. If you want to keep a school of 5-6 fish, which is the recommended number, you should have a 30 gallon tank.

Gold barbs are active fish that prefer to be in a group, so the more space you can give them the better.

Water Parameters

Gold barbs are a tropical fish, so they prefer warm water. The temperature range for gold barbs is 72 to 82 degrees Fahrenheit.

pH levels for gold barbs should be between 6.5 and 7.5.

Water hardness for gold barbs should be between 4 and 8 dGH.

Alkalinity levels for gold barbs should be between 4 and 8 dKH.

What To Put In Their Tank

Aquariums for gold barbs don’t require a lot of decoration. They’re not a species that needs a ton of hiding places or anything like that.

A few pieces of wood or some rocks can help add a little bit of variety to their tank, but it’s not necessary.

The biggest thing you need to worry about is the vegetation. Gold barbs LOVE to nibble on plants. They’re not as destructive as some other species (like cichlids), but they can still do a number on your aquatic greenery.

We recommend avoiding plants altogether or sticking with something that can handle a little abuse (like Hornwort or Java Moss).

The substrate is another important consideration. Gold barbs are notorious for digging and stirring things up. A soft, sandy substrate is going to be a lot more comfortable for them (and you).

Common Diseases

There are a few diseases that are more common in gold barbs than other fish. The most common is hole-in-the-head disease, which is caused by poor water quality and the presence of activated carbon in the tank.

This will present itself as one or two pits/holes in the skin of your fish’s head. While it’s almost always curable (fixing your water quality and removing activated carbon is usually all you need to do), it will usually leave some scarring on your poor fish!

Another disease to look out for is Neon Tetra Disease. This is a pretty serious illness that is unfortunately quite common in gold barbs.

This disease is caused by a bacteria called Mycobacterium, which can attack the organs, skin, and eyes of your fish. The most common symptom is a reddish hue on the body of your fish, but it can also lead to blindness and death if left untreated.

If you notice any strange changes in your fish (especially a red coloration) it’s important to take them to the vet immediately. There is no known cure for this disease, but early detection and treatment can help to prolong the life of your fish.

The best way to prevent these diseases is by maintaining a clean and stable tank. Gold barbs are pretty resilient fish, but they’re not immune to poor water quality.

By keeping the tank clean and the water quality high, you can dramatically reduce the chance of your fish getting sick.

Behavior & Temperament

The gold barb is a schooling fish, so it does best in groups. These fish are peaceful and prefer to stay near the bottom of the tank. They’re not fussy eaters, so they’ll eat just about anything you give them.

The gold barb is a hardy fish that can withstand a wide range of water conditions. It’s not uncommon for these fish to live for 10 years or more with proper care.

These fish are relatively low-maintenance, but they do need a bit of space to swim. A 20-gallon tank is the minimum size you should consider for a group of gold barbs.

Tank Mates

The gold barb is a peaceful, community-oriented fish. As such, it does well with a wide variety of tank mates.

These fish are small and nimble, so they can easily dart away from potential threats. They’re also not aggressive and generally leave other fish alone.

The main thing you need to worry about is finding fish that occupy different parts of the water column. Gold barbs are bottom dwellers, so they don’t venture to the top or middle very often.

This gives you plenty of options when stocking your tank. Some compatible gold barb tank mates include:


Breeding gold barbs is a relatively easy process as long as you provide them with the right environment. These fish are known to be pretty good parents, so they will take care of everything once the eggs have been laid.

To start, you will need to set up a breeding tank. It should hold at least 20 gallons of water. Then, add some live plants and a few pieces of driftwood. The plants are important because they will give the fry a place to hide.

When ready, add two males and four females to the tank. It’s best to have more females than males to ensure that all the eggs get fertilized.

Once the fish have had a chance to acclimate, begin feeding them a high-quality diet. Then, start changing about 50 percent of the water every week.

You’ll know that spawning is about to happen when you see the males chasing the females around. The females will lay their eggs on the plants or driftwood. After that, the males will fertilize them.

Once the eggs have been fertilized, the parents will do a good job of guarding them. They will even clean the area around the eggs to make sure they have the best chance of survival.

The eggs will hatch in about a week. Once they hatch, you can remove the adults and begin feeding the fry baby brine shrimp.


Gold barb care is pretty easy, but there are a few things you need to be aware of.

First and foremost, these fish are very active and need plenty of space to swim around. A small tank is not going to cut it.

You also need to be careful with the other fish you put in the tank with them. They can be pretty nippy, so peaceful fish are a better choice.

Other than that, gold barbs are pretty low-maintenance and make great additions to community tanks. We hope you enjoy them as much as we do!
