The Black Ruby Barbs arrived healthy and were active from the start. I kept them in a 55-liter tank with java fern and they look stunning. The red highlights are especially vibrant after a few weeks. They swim together in a school, which adds a lot of visual interest to the tank.

I bought a group of six and they’ve been thriving in my planted tank. The males show bright red coloring now, which is impressive. They don’t bother plants and are very peaceful. A great addition to any community aquarium.

The fish are very active and colorful. I noticed the red tones become more intense after two months. They swim in a tight school and look natural. Easy to care for and fit well with my existing plants.
