General Care

Barb fish, in general, are easy to care for and can be the ideal species for beginners, or to add to a communal tank. I am going to do a very quick overview; however, each species of barb fish is unique and will need more specific care;

Aquarium Set-Up

Your barb fish need to have the right habitat with the correct water conditions to thrive and stay disease free. Water temperatures of around 16.7  ̊C – 27.8  ̊ C (62  ̊ F – 82  ̊ F) are the ranges in which most barb fish thrive. They require a slightly neutral to acidic pH of between pH 6.0 and pH 7.5, with a water hardness of around 10 dGH or less. As their natural habitats are mostly rivers, and streams all over the world, most species prefer moderate currents from a good filtration system and very clean water. They do need a heater unless you live in an area with a more tropical climate, and they do need daily indirect sunlight, or an artificial light to indicate day and night. Barbs love a well-planted tank with thick sand or gravel substrate, mostly live plants, and some natural rocks and driftwood.


Barbs are omnivores and require a diet of flakes and pellets, as well as protein-based foods including insect larvae, bloodworms, and brine shrimp, and vegetables including algae, zucchini, lettuce, shelled peas, and spinach mostly. They are vigorous eaters and need to be fed two meals and one snack a day enough to finish within a few minutes.

Common Health Issues

Generally, most health issues in barbs are caused by poor diet, and poor water conditions, they are hardy fish however should be taken care of properly. Most common diseases include parasites such as Ich, or bacterial and fungal infections such as Fin Rot, and Dropsy, an infection of the swim bladder. Maintaining your tank is key to a healthy and content Barb fish, and following the steps on Wikihow has provided the most accurate information on tank maintenance so far.


Any species of Barb fish is relatively easy to breed with a few very small differences from species to species. However, they are all eggs scattered that require a separate tank for layering eggs with a male and female pair, or a few males and females. The tank needs enough vegetation for eggs to latch on to and young fry to hide, and the parents must be removed directly after laying eggs. The gestation period of the eggs varies in some species of barbs, though will mostly be 24 hours, with another 24 hours before fry are independent.

5 Best Barbs for Your Aquarium

So, after much research and thought, I have decided to go with five of the most popular and easily attainable Barb fish species, in varying sizes for your aquarium;

1. Cherry Barb

We start off with the delightful, small Cherry Barb, one of the most Peaceful Barb species, with Warm and Bold colors. The Cherry Barb originates from Sri Lanka and is one of our smallest in the list at 5cm (2 Inches) with a 4 – 7-year lifespan, which is quite long for smaller Barb fish species. Cherry Barbs have a primary red or tan color and different flecks of reds and orange, there are similarly quite a few other color morphs in the Cherry Barb, such as Red, orange, and yellow. They are colorful tiny barbs that are Schooling fish, with a preference for calmer and cooler water temperatures.

2. Rosy Barb

Another favorite Barb fish species is the Rosy Barb for its warm and radiant colors, and their very peaceful and social nature with other fish. They get lonely and stressed when alone, rather than aggressive, and enjoy the company of tank mates of all species. Rosy barbs are smaller Barbs around 14-15 cm (6 inches) and can live for up to 5 years if taken care of very well. Did you know that you can improve the rich Rosy colors of your Rosy Barbs by feeding them carotenoids? They also have other color morphs such as the Red Glass Rosy Barb, and the Gold Neon Rosy Barb. They are the perfect beginner Barb species, for a larger 30-gallon tank, and they prefer much cooler water temperatures similar to their native origin Southern Asia.

3. Odessa Barb

The Odessa Barb “Pethia Padamya” is a very colorful species, with Ruby Like red color markings found mostly in males. They are peaceful shoaling Barbs that will reach sizes of around 7 cm (2.8 inches), and will likewise easily live up to 4 or 5 years with optimal care. Rosy Barbs are native to Southeast Asia and enjoy colder water temperatures, similarly requiring a tank of between 20-30 gallons for a group of five or six fish.

4. Tinfoil Barb

One of the largest Barb species that also deserves its rightful place is the Tinfoil Barb “Barbonymus schwanenfeldii”, a gorgeous and glistening fish with intricate red and black markings. Let me just tell you it is a large fish reaching between 32 – 35cm (12 – 14 Inches) in size, and has a long lifespan of up to 15 years. You will need at least a 75-gallon tank for five fish, with cooler water and slightly acidic to neutral pH. The Tinfoil Barb is also native to Southeast Asia.

5. Black Ruby Barb

For those of you with much smaller tanks, or smaller communal fish in your aquarium, I end off with one of my personal favorites, the Black Ruby Barb (Pethia nigrofasciata), a tiny Barb species that exhibits the most striking and unique colors in every individual fish. It reaches up to 5 cm(2 Inches) in size and has a lifespan of between 3-5 years.  The Black Ruby Barb originates from Sri Lanka and prefers cooler water conditions that are fresh and shaded. I must add, they look exquisite in aquariums with darker substrates and decor, as it shows off their gorgeous colors.

In Conclusion

Barbs are one of the most peaceful and interesting fish species to keep in your communal tank with suitable tank mates of other species. They need to be kept in groups and will actively swim in Schools to keep you entertained. Barbs are easy to care for and from the 5 popular breeds that we have mentioned you should easily be able to find one that is suitable for your aquarium.
