Colombian Redfin Tetra (Hyphessobrycon columbianus)

The Colombian Redfin Tetra is commonly a hardy, adaptable and active fish and it fairs well in a community aquarium. They can be a bit nippy at long fins, so keeping them in a larger group will essentially cease that behaviour.

Make sure you don't house Colombian Redfin Tetra with boisterous species since they can be easily intimidated. You should also avoid keeping these Tetras with fancy long-finned species since their elaborate finnage can be a temptation. Instead, fish such as Characids, Dwarf Cichlids, Hatchet Fish, Pencilfish, Loricariids and Corydoras Catfish would be ideal tank mates for these fish.

As Colombian Redfin Tetras are a schooling species, it is best to keep them in groups of six or more individuals. When these fish are kept in larger groups, you are more likely to see the harmless natural displays between rival males and their dazzling colours intensifying.

Well-furnished, established aquariums are better for Colombian Redfin Tetras. In a natural-looking arrangement, driftwood branches and roots, bogwood, and aquatic plants, including floating plants, might be placed along the substrate, creating plenty of shady spots.

By adding dried leaves such as oak or Indian almond, you can further enhance the natural feel and allow beneficial microbes to flourish as they decompose. The tannins and other chemicals emitted by rotting leaves are considered beneficial to babies, while these microbes provide a source of secondary nutrition.

Tetras are intolerant to organic pollutants and require clean water, just like numerous species that inhabit pristine environments. The water will need to be changed weekly, and some decent filtration will be required. Nevertheless, it would be best if you did not introduce these Tetras to a biologically immature aquarium.

A silvery-grey colouration is complemented by a turquoise-blue tinge that develops over the dorsal ridge of the Colombian Redfin Tetra. The fish's fins are predominantly blood-red, but as it pauses, the colour fades. Caudal and dorsal fins have whitish tips, while ventral fins are transparent to light orange. Anal fins are usually edged in black.

Feeding

In the home aquarium, the Colombian Redfin Tetra will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.

Sexual Dimorphism

It is somewhat tricky to determine the males from the females. Still, usually, sexually mature males are more intensely-coloured, have slimmer-bodies, are a little smaller and develop an elongated dorsal-fin then that of the females.
