Colombian Redfin Tetra - Hyphessobrycon columbianus : Complete Fish Profile & Care Guide

Table of contents


The Columbian Redfin Tetra (Hyphessobrycon columbianus) is a striking and dynamic addition to any community aquarium. Hardy, adaptable, and active, they are best kept in groups of six or more individuals to observe their natural schooling behavior and enjoy their dazzling displays. These Tetras are best kept with peaceful and similar-sized species such as Characids, Dwarf Cichlids, Hatchet Fish, Pencilfish, Loricariids, and Corydoras Catfish. To prevent fin nipping, it is also important to keep them away from boisterous or long-finned species. To create a natural environment for the Columbian Redfin Tetras, a well-furnished aquarium with driftwood, bogwood, and aquatic plants is recommended. Dried leaves such as oak or Indian almond can also be added to enhance the natural feel and provide a source of secondary nutrition for beneficial microbes. Clean water is essential for these Tetras, and regular weekly water changes and proper filtration are necessary to maintain a healthy environment. These fish are intolerant to organic pollutants and should not be introduced to a biologically immature aquarium. The Columbian Redfin Tetra has a silvery-grey body with a turquoise-blue tinge over the dorsal ridge, complemented by blood-red fins with whitish tips. The ventral fins are transparent to light orange, and the anal fins are usually edged in black. Their coloration and schooling behavior make them a stunning addition to any community aquarium.

Sexual Dimorphism

Sexually dimorphic characteristics in the Columbian Redfin Tetra make it somewhat challenging to differentiate males from females. Males are distinguished by their vibrant, intense colouration, slimmer bodies, and slightly smaller size, in addition to developing an elongated dorsal fin. In contrast, females have a rounder body shape and lack the elongated dorsal fin.

Natural habitat

The Columbian Redfin Tetra originates from the Rio Acandi in Choco Department, Northern Colombia, close to the border with Panama. In their natural habitat, these remarkable creatures inhabit small, slow-flowing creeks, streams, tributaries, and waterways that are heavily vegetated and have submerged tree roots. These serene waters provide an ideal environment for these fish to forage for food and explore their surroundings. The Colombian Redfin Tetra serves as a testament to the incredible biodiversity of South America and the importance of preserving and protecting our planet's natural resources. Their unique natural habitat requirements and fascinating behavior make them a truly captivating addition to any aquatic collection. Prepare to be mesmerized by the stunning beauty of the Colombian Redfin Tetra and the wonders of the natural world. With their distinctive red fins and lively personality, these fish are sure to impress even the most discerning aquarists. As you observe these fish in their natural habitat, you'll gain a deeper appreciation for the importance of conservation efforts to protect and preserve our planet's delicate ecosystems.

How to breed the Colombian Redfin Tetra

Breeding the Columbian Redfin Tetra (Hyphessobrycon columbianus) is a relatively straightforward process that requires a separate breeding tank with specific conditions. The tank must be heavily planted with fine-leaved plants such as java moss, dimly lit, and have gentle filtration with soft acidic water. It is also essential to condition the fish with high-quality live or flake food three to five times per day. When a female is ready to spawn, she becomes plump, and at this point, you should introduce your healthiest male and female to the breeding tank. When the couple is ready to spawn, the male will perform a courting display by flicking his fins and shimmies near the female. After the courting dance, the female will discharge her eggs, and the male will fertilize them. A single spawning will produce approximately 100 to 150 semi-adhesive eggs that the parents will consume if given the opportunity. It is, therefore, best to remove the eggs once spawning has finished. The eggs are sensitive to light, so the breeding tank should be covered or kept dark to prevent damage. Hatching usually occurs around 36 hours later, and the fry will become free-swimming four days later. The fry should be fed infusoria or unicellular organisms initially, then finely crushed flake food, and finally, freshly hatched brine shrimp and micro worms several days later to help them grow.

Diet & feeding

To maintain the vibrant colours and overall health of the Columbian Redfin Tetra in the home aquarium, a balanced and varied diet is necessary. Offering small, but frequent feedings of high-quality dried granules and flakes that include algae or plant content, along with frozen and live foods such as daphnia, bloodworm, and brine shrimp will provide the best results. By incorporating such foods into their diet, you can ensure that your Colombian Redfin Tetras are receiving all the essential nutrients they need for optimal growth and development.
