Asia; Denison barbs are mostly found in South India.


There are no visible differences between the sexes.


As of yet, there are no reported cases of Puntius denisonii breeding in the aquarium.


The expected life span for Puntius denisonii is 5-7 years.

Short description

Denison barbs are very active so a large tank is required with open swimming spaces. Plants, rocks, and wood should also be added to provide hiding places. Lower temperatures are accepted by this fish so in warmer countries a heater may not be required in the tank. As this fish has become very popular there is some concern to the wild stocks being depleted to fulfil the demand in the aquarium industry.
