Tank conditions

To keep Clown Barbs healthy and happy, providing them with proper tank conditions is important. Minimum tank size is 55 gallon tank.

These fish are native to freshwater environments and prefer a water temperature between 22 and 28 degrees Celsius. They also prefer a neutral pH level of around 7.0, with a water hardness between 10 and 20 dGH.

Clown Barbs are relatively hardy fish, but it is still important to perform regular water changes and maintain good filtration to keep the water clean and healthy. In terms of tank size, these fish are well-suited to aquariums of a minimum of 55 gallons, and providing additional 8 gallons of water per fish is recommended to ensure plenty of swimming space.

Providing plenty of hiding places, such as rocks, plants, or decorations, is also important to promote a natural and secure environment. By providing proper tank conditions, hobbyists can help their Clown Barbs thrive and bring energy and life to their aquariums for many years.


Clown Barbs are omnivores, and their diet should consist of plant- and animal-based foods. In the wild, these fish feed on a variety of food sources, including insects, algae, and small crustaceans.

In the aquarium, a balanced diet can be achieved by feeding a mixture of high-quality flakes, pellets, and frozen or live foods such as bloodworms, brine shrimp, and daphnia.

It is important to avoid overfeeding, as this can lead to water quality issues and health problems for the fish. Feeding two or three small meals per day, rather than one large feeding, is recommended to help prevent overfeeding and keep the water clean and healthy.

By providing a balanced diet and avoiding overfeeding, hobbyists can help to ensure that their Clown Barbs receive the nutrients they need to thrive and stay healthy.


Breeding Clown Barbs can be a challenging but rewarding experience for hobbyists. These fish are egg-layers and breed in pairs or small groups. To breed Clown Barbs successfully, hobbyists should provide a suitable breeding environment with appropriate water conditions and plenty of hiding places.

The breeding pair should be well-conditioned, and the water parameters should be optimized to mimic the fish’s natural habitat. A temperature increase of several degrees above the normal aquarium can also stimulate breeding.

Once the eggs are laid, the parents should be removed to prevent them from eating them. The eggs should hatch in about 24 to 36 hours, and the fry will become free-swimming after another couple of days. At this point, they can be fed small amounts of infusoria or similar foods until they are large enough to consume newly hatched brine shrimp.

Breeding Clown Barbs can be a challenging but rewarding experience that requires patience and attention to detail. Hobbyists can successfully breed this beautiful and fascinating fish species by providing the right conditions and proper care.


Diseases can be a concern for any fish species, including Clown Barbs. To minimize the risk of disease in your aquarium, providing good water quality and a healthy diet is important. Additionally, it is important to avoid overstocking the tank and to monitor the fish for signs of stress or illness.

Clown Barbs’ common diseases include Ich, Fin Rot, and Swim Bladder Disorder. Ich is a parasite that causes white spots on the skin and fins, while Fin Rot is a bacterial infection that causes the fins to deteriorate. Swim Bladder Disorder is a condition that affects the fish’s ability to control its buoyancy, causing it to float or sink awkwardly.
