General Description
Hyphessobrycon Balbus, commonly known as Balbus Tetra, belongs to the family Characidae under the classification order Characiformes. The species is named for its incomplete lateral line, which appears as if it is "stuttering," reflected in the Latin word "balbus."
Aquarium Setup
For keeping Hyphessobrycon Balbus in captivity, a tank size of at least 10 gallons is recommended. The aquarium should be well-planted, simulating its natural habitat, with driftwood and rocks to provide hiding spots. Being a shoaling fish, they should be kept in groups of six or more. Water parameters should be maintained at a temperature range of 22-26°C (72-79°F), pH of 5.5-7.5, and hardness of 2-15 dGH (see table).
Behaviour
Balbus Tetras are peaceful and active swimmers, best suited for community aquariums. They exhibit typical shoaling behavior and feel more secure in the presence of conspecifics or other tank mates. Providing them with ample hiding spaces helps reduce stress and encourages natural behavior.
Feeding and Diet
In the wild, Hyphessobrycon Balbus feeds on small invertebrates and plant matter. In captivity, they readily accept high-quality flake food, supplemented with live or frozen brine shrimp, bloodworms, and daphnia. A varied diet is essential to ensure their health and vibrant coloration.
Reproduction & Dimorphism
Breeding Hyphessobrycon Balbus in captivity is achievable by providing them with dense vegetation for spawning. The females are rounder in the belly region when compared to males, especially when carrying eggs. Spawning usually occurs early in the morning, with the parents showing little to no interest in caring for the eggs or fry.
Habitat and Distribution
Endemic to the headwaters of the upper Paraná river basin in central Brazil, Hyphessobrycon Balbus is primarily found in the Federal District and the neighboring state of Goiás. Specific localities include the rivers Sâo Bartolomeu, Bananal, Santa Maria-Torto, and Gama tributary systems. In these habitats, they coexist with various other fish species such as Characidium and Bryconamericus.
