Green Tiger Barb (Puntius semifasciolatus) A very lively fish that will do well in many community fish tanks! also known as the Sumatra Barb is a truly unique variety of barb. With shiny green bodies and an underlying tiger pattern these barbs look amazing in a group of 5+. Larger specimens grow just under 4” and are a perfect choice for smaller tanks around the 20 gallon range. One of our favorite Barbs that stand out against the crowd!
