Flame Tetra Care Guide
Hyphessobrycon flammeus · Freshwater Fish
What Flame Tetra look like
The Flame Tetra, scientifically known as Hyphessobrycon flammeus, exhibits a strikingly vibrant coloration that is characterized by a silver to olive front half, transitioning to a fiery orange-red hue on the posterior body and fins. This species typically reaches a maximum adult size of approximately 5 cm (2 inches). Sexual dimorphism is subtle; males tend to display more intense coloration and slightly elongated fins compared to females. A notable morphological feature includes the presence of two distinct dark vertical bars located just behind the gills, which serve as a form of disruptive coloration. The body is laterally compressed and fusiform, allowing for agile movement through its native habitats. Additionally, the Flame Tetra possesses an adipose fin, which aids in stabilization during swimming, and a well-developed lateral line system that enhances its sensory perception in the aquatic environment.
Behavior & temperament
Flame Tetras are social fish that thrive in groups, exhibiting a strong tendency to form schools in their natural habitats, which are typically found in the shallow, slow-moving waters of Brazil. They dwell primarily in the mid to upper water column, where they engage in active schooling behavior. Their breeding behavior is characterized as an egg scatterer, with females releasing eggs in open water, allowing for external fertilization by males. In terms of temperament, Flame Tetras are generally peaceful and non-aggressive, making them suitable for community tanks; however, they can display some territoriality during breeding periods, particularly among males.
Diet & feeding
In the wild, Flame Tetras are omnivorous, feeding on a varied diet that includes small invertebrates, plant matter, and detritus. In captivity, they require a balanced diet consisting of high-quality flake food, supplemented with live or frozen foods such as daphnia and brine shrimp to ensure optimal health and coloration.
