Fatos principais
Taxonomic Reclassificationevolution
Historically, Puntigrus tetrazona was classified under the genus Puntius (as Puntius tetrazona). Recent phylogenetic studies led to its reclassification into the genus Puntigrus, along with other similar striped barb species.
Fin-Nipping Behaviorbehavior
Tiger Barbs are notorious for their fin-nipping behavior, especially when kept in insufficient numbers or with slow-moving, long-finned tank mates. Keeping them in large schools (6 or more) helps to distribute this aggression among themselves.
Color Morphsinteresting
Selective breeding in the aquarium trade has produced several popular color morphs, including the Green Tiger Barb (moss green) and Albino Tiger Barb, which are widely available.
Energetic Swimmersbehavior
These fish are highly active and require ample swimming space in an aquarium. Their constant movement adds a dynamic element to any community tank.
