Purple Harlequin Rasbora

Discover the captivating beauty of the Purple Harlequin Rasbora (Trigonostigma heteromorpha), a remarkable addition to any aquarium. Dressed in a remarkable array of purple hues, this variant of the wild variety is sure to mesmerize and become the focal point of your aquatic masterpiece. Stand back and admire as its vibrant colors harmonize exquisitely with a dark-colored substrate, creating a visual spectacle that sets it apart from all others.

Intriguingly, the males of the Purple Harlequin Rasbora showcase even more vivid colors compared to their female counterparts. Their distinct "lambchop" markings feature sharply pointed edges, further enhancing their appeal. Meanwhile, the females exhibit a rounder shape, adding diversity to their appearance.

Perfectly suited for nano tanks, the Purple Harlequin Rasbora's diminutive size makes it an ideal choice for compact aquatic setups. Enjoy the opportunity to showcase its splendor in a smaller, more intimate environment while still providing the necessary care it deserves.

Caring for the Purple Harlequin Rasbora is a breeze, as long as you maintain stable water parameters and ensure good water quality. These peaceful creatures are compatible with a variety of tank mates, including other peaceful fish, snails, shrimp, and live plants. It's important to note that while they coexist peacefully with adult shrimp, they may pose a risk to shrimp fry. To witness their most natural behavior and vibrant top coloration, it is recommended to keep them in groups of at least 6-8 specimens. A large school of these rasboras will bring out their best as the males compete for the attention of females, creating a captivating display.

When provided with a well-cycled and densely planted aquarium, the Purple Harlequin Rasbora may even grace you with the sight of fry. These resilient fish are known to spawn under optimal conditions, adding another layer of intrigue to your aquatic experience.

As an omnivorous species, the Purple Harlequin Rasbora is not particularly picky when it comes to food. It readily accepts fish flakes or pellets, but for optimal breeding and vibrant coloration, a varied diet of frozen meaty and live foods is recommended. Treat them to brine shrimp, bloodworms, daphnia, and insect larvae to encourage breeding behavior and display their full spectrum of colors. Additionally, blanched vegetables such as lettuce, zucchini, and kale can be offered to supplement their diet.

With its undemanding nature and timeless appeal, the Purple Harlequin Rasbora is a classic choice for planted or nano aquariums. Embrace the opportunity to create a captivating aquatic environment with this charming species as its centerpiece. Experience the joy and tranquility that this enchanting fish brings as it gracefully navigates its colorful world. Elevate your aquarium to new heights with the Purple Harlequin Rasbora, an embodiment of aquatic elegance and natural beauty.
