The black ruby barbs are vibrant and active in the tank. I noticed their colors deepen after a few weeks. They get along well with other peaceful fish and are easy to maintain.

I bought a pair and they’ve been thriving in my 10-gallon tank. The red color is quite noticeable, especially when the lighting is good. Feeding them color-enhancing flakes made a difference.

Great addition to my community tank. The fish are calm and don’t fight with other species. They grow steadily and look more colorful over time.
