Flameback Bleeding Heart Tetra (Hyphessobrycon pyrrhonotus)

As well-researched community aquarium fish, Flameback Bleeding Heart Tetras are peaceful and mix well with similar-sized and harmonious fish. If not kept in a large enough group, they may bully smaller Tetras. In spite of this, these Tetras make an impressive centrepiece for medium to large planted aquariums.

Make sure you don't house these Tetras with boisterous species as they can be easily intimidated. The elaborate finnage of long-finned species can also be too tempting for these Tetras, so it is not recommended that they are kept with them. Instead, the ideal tankmates for these fish would be similarly-sized Characids, Dwarf Cichlids, Hatchet Fish, Pencilfish, smaller Loricariids, and Corydoras Catfish.

In nature, Flameback Bleeding Heart Tetras form schools, so it is best to keep them in groups of six or more. Larger groups of these fish allow you to observe the harmless natural displays between rival males and their dazzling colours intensifying even further.

An aquarium that is well-established and furnished is better suited for these Tetras. In order to create a natural-looking arrangement, driftwood branches and roots, bogwood and aquatic plants, such as floating plants, can be arranged over a soft, sandy substrate.

The addition of dried leaves, such as oak or Indian almond, would enhance the natural feel and allow beneficial microbe colonies to thrive. A secondary food source for babies can be provided by these microbes, while tannins and other chemicals released by decaying leaves are beneficial.

As with numerous other species of fish that live in pristine environments, these Tetras cannot tolerate organic pollutants in the water. Therefore, some decent filtration is required, and water changes should be performed weekly. In any case, it would be best if you avoided introducing these Tetras to an aquarium that is biologically immature.

In addition to their attractive pink colouration, Flame Back Bleeding Heart Tetras have a heart-shaped marking on their sides. These Tetras also have red eyes and an iridescent red stripe extending across their dorsal surface through the caudal, leading to an extended black dorsal fin edged in white.

Natural Habitat

Rio Negro


In the home aquarium, the Flameback Bleeding Heart 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 effortless to differentiate between male and female Red Back Bleeding Heart Tetras. The males will grow noticeably larger and are more intensely coloured than females, and their dorsal, pelvic and anal fins are highly extended. In contrast, adult females usually have rounder bellies, especially when they are gravid.
