Black Ruby Barb (3ct)

The Black Ruby Barb is a striking and lively freshwater fish that makes a wonderful addition to community aquariums. Known for its deep ruby-red body with bold black accents, this species is a true eye-catcher. When kept in a group, their colors become even richer and more vibrant, especially as the fish mature.

The Black Ruby Barb (3ct) is a great way to start building a small group. While they can be kept in trios, Black Ruby Barbs thrive best in larger schools, so many aquarists choose to add more over time. Their active swimming style and playful nature bring constant movement and energy to your tank. They are generally peaceful with most similarly sized fish but may show semi-aggressive behavior toward slow-moving or long-finned companions, such as angelfish or bettas. Keeping them in groups helps reduce fin-nipping and encourages their natural schooling instincts.

One of the most exciting features of Black Ruby Barbs is how much their appearance improves over time. Males, in particular, will darken far beyond what is often pictured online or in stores. Once acclimated and fully mature, their color deepens into a rich purplish-red with striking contrast, making them stand out beautifully in any aquarium.

Set-Up Your Tank

• Make sure it all works: We suggest your tank be set-up for at least 24 hours before ordering fish to ensure all equipment is working.
• Use a heater: GloFish® fish enjoy tropical temperatures of 76-80F.
• Make Them Shine Their Brightest: GloFish® fish absorb light and then re-emit it, so their unique fluorescent colors will appear brighter and more vibrant as the amount of light is increased. So the more blue light you have the more your fish will shine!

Add Your Fish

• Follow this acclimation guide to make sure they adjust to their new home.

Feed Your Fish

• Feed two to three times daily, in small amounts, only as much as your fish can eat in a minute or so.
• Danios, tetras, and barbs GloFish Special Flake food or GloFish® MicroCrisp Food
