Tiger barb fish require a large tank – at least 20 gallons and up to 30 gallons. They also need plenty of privacy and room to move around. The best way to house them is by providing them with rocks, plants, and hiding spots. Ensure their water temperature is kept around 77-82 degrees Fahrenheit, as they can get quite hot in the summertime.

Diet and Feeding

You should feed adult tiger barbs 2-4 times per day, depending on the size of the individual fish. This means that they will eat a lot. Their diet consists mainly of small fish, so give them live food to keep them entertained and engaged. It would help if you kept their tank clean to prevent the buildup of waste that can harm your fish. In addition, to live food, tiger barbs enjoy eating algae flakes, bloodworms, and brine shrimp.

Tank Size

You should keep tiger barb fish in tanks at least 20 gallons in size, but 30-gallon tanks are better as they provide more room to swim and hide. Make sure you have enough space, too, by considering the size of the fish you’re trying to keep and the other aquatic creatures in your tank.

Water Parameters

Tiger barb fish need clean, clear water with a temperature around 77-82 degrees Fahrenheit and a pH level between 6.0-7.8. In addition, they like to have a medium-high level of hardness. In addition, they do well in aquariums with a limited number of plant species.


Once you’ve got your tiger barb fish in the tank, it’s time to set up the rest of their habitat. You’ll want to add a few hiding places for them, like caves and plants that can provide cover. You should also fill their tank with fresh water once a day and add chlorine or ammonia (if necessary) to keep the water clean. Lastly, be sure to adjust the lighting in their tank according to their natural environment and ensure plenty of oxygen is flowing through the water.

Common Possible Diseases

Like most fish, tiger barbs can get sick and require treatment from a veterinarian. However, most diseases affecting them are minor and can be treated at home using over-the-counter medications. Some possible diseases include swim bladder disease, parasitic infections, Ich (a type of parasitic infection), and fungal growths.

Behavior & Temperament

Tiger barb fish are typically peaceful and calm but can become territorial when housed with other fish. They breed quickly and can produce up to 12 eggs per week. In addition, tiger barb fish are semi-aquatic and will need access to a water source if kept in an indoor setting.

Tiger Barb Tank Mates

Due to their aggression towards other tank mates, tiger barb fish are not recommended for home aquariums with other fish species. Instead, they should be kept with rosy barb, cherry barb, cory catfish, clown loach, and most types of plecos. In addition, they can be housed with other semi-aquatic species, such as cichlids and catfish.
