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.

The Colombian Redfin Tetra has a silvery-grey body and displays a turquoise-blue tinge of developing intensity from the lateral line upwards, which becomes a noticeable stripe across the anterior dorsal ridge.

The fins are mostly a bright blood red colour, but the colour fades as the fish pauses. The ventral fins are transparent to light orange, and the anal fin is ordinarily edged with black, and both the caudal and dorsal fins have whitish tips.

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.
