Denisoni Barb
Denisoni barbs are also known as the red-line torpedo barb, Denison barb, or roseline shark. These fish are active swimmers and get more and more color as they age, showing bright reds and yellows. We recommend a school of three or more. Roseline sharks are hardy and eat flake and live foods. A school of roseline sharks is a nice addition to planted tanks, peaceful community tanks, and larger species fish tanks, but these fish do require well-filtered aquarium water.

I added a school of three Denisoni barbs to my planted tank. They are very active and show vibrant red and yellow colors after a few months. They coexist well with other peaceful fish and don’t stress the community. Water quality is key, so I make sure to maintain good filtration.

The fish arrived healthy and were active from day one. I kept them in a 20-gallon tank with live plants and a good filter. They swim constantly and their colors brighten over time. A bit shy at first, but they settle in quickly.

Great addition to a community tank. They don’t fight with other fish and are easy to care for. I feed them flake and occasional live food. After six months, their red and yellow hues are much more vivid than when I first got them.
