The checkered barb (Oliotius oligolepis), formerly known as the checkered barb (Puntius oligolepis) is a member of the barb species group. These ray-finned fish are known for being beginner-friendly aquarium fish. The name Puntius oligolepis is etymologically derived from a Greek word that literally translates to 'less fish scale'.
Checkered barbs go by different names such as checkerboard barb, island barb, or just checker barb. Its appearance, specifically its black and silver markings, is the inspiration for its name, as it resembles a checkerboard.
These small fish are school fish who travel and live in groups in the wild. Being endemic to Sumatra, they are mostly found in wetlands of the west coast of Indonesia. They reproduce in large numbers and are also bred for commercial purposes.

How do they reproduce?
As an egg-scattering spawner, it is relatively easy to breed this species. Little prior experience or expertise is therefore required.
Females of the species lay eggs whenever the spawning conditions are ideal. Experts recommend the use of a breeding tank to avoid conflicts between males and to gain control over the process.
Another thing to keep in mind is the predatory nature of the parents. Adults should be removed from the breeding tank containing the eggs and owners should ensure that there is enough vegetation in the aquarium to hold the eggs until they mature.
Spawning mops are an alternative, which can be bought or made at home as a DIY project. The eggs mature rather quickly and will hatch in 24-48 hours.
What is their conservation status?
According to the International Union for Conservation of Nature (IUCN) Red List, this fish species has been declared as Least Concern. Intensive research is required to map out its exact population trends and possible threats. At present, some of its range falls under nationally protected zones, which amounts to some protection.
