Firehead Tetra Care Guide
Hemigrammus bleheri · Freshwater Fish
What Firehead Tetra look like
Hemigrammus bleheri, commonly known as the Firehead Tetra, exhibits a laterally compressed, fusiform body that typically reaches a maximum adult size of approximately 2 inches (5 cm). This species is characterized by its striking coloration, featuring a silver body adorned with a vivid red head that extends from the snout to just behind the gill cover, resembling flames. The caudal fin displays bold black and white horizontal stripes, enhancing its visual appeal. Sexual dimorphism is subtle, with females generally appearing slightly fuller-bodied than males, particularly when gravid. Defensive adaptations include a schooling behavior that provides safety in numbers, while the presence of a lateral line system aids in detecting movement and vibrations in the water. The Firehead Tetra also possesses a small, well-defined adipose fin, contributing to its streamlined appearance.
Behavior & temperament
The Firehead Tetra is a highly social species, exhibiting obligate schooling behavior, which is essential for its well-being. It typically inhabits the mid to upper levels of the water column in its natural habitat, where it forages and interacts with conspecifics. Breeding occurs in a communal setting, where the species is known to be an egg scatterer, releasing adhesive eggs among aquatic vegetation. The temperament of Hemigrammus bleheri is generally peaceful, making it an ideal community fish; however, it can display mild territoriality during breeding periods, particularly in confined spaces.
Diet & feeding
In the wild, the Firehead Tetra is an omnivore, feeding on a varied diet that includes small invertebrates, plant matter, and detritus. In captivity, it thrives on a balanced diet of high-quality flake food, supplemented with live or frozen foods such as brine shrimp and daphnia, along with occasional plant-based offerings to ensure optimal health.
