Diamond Shark

The Diamond Shark (Hypsibarbus wetmorei) is also commonly known as the Pale Barb or Golden Belly Barb. Like most popular aquarium sharks, the diamond shark is actually a type of barb, and will live absolutely fine in community tropical aquariums.

Diamond shark's can grow quite large, and are fast swimmers, so ensure you have an aquarium large enough to accommodate them. They will thrive in small groups of 3 to 5, but can be kept solitary without issue. Diamond Sharks have been given the names Lemon Fin Barb, Yellow Belly Barb, Yellow Tinfoil Barb, and Golden Belly Barb, among others.

The Diamond Shark is widespread in mainland Southeast Asia, including the lower Mekong basin in Laos, Thailand, and Cambodia, and Malaysia, as far south as the Pahang River. They prefer flowing waterways and rivers to standing pools. The Diamond Shark is a migratory fish, especially during the spawning season.

Are Diamond Sharks aggressive?
Diamond sharks are not generally aggressive, but they are fast swimmers, which means they can unsettle nervous fish and may outcompete others at feeding time. They can be kept in community aquariums, but ensure the fish tank is large enough to accommodate long-term growth.

How big do Diamond Sharks get?
In captive aquaria, Diamond Shark's tend to grow to a maximum of around 25-30cm, or 12" inches. However, in the wild, the Diamond Shark or Golden Belly Barb has been known to grow to twice the size, with females reaching around 25" inches.
