What Black Heart Tetra look like
Hyphessobrycon copelandi, commonly known as the Black Heart Tetra, exhibits a laterally compressed, fusiform body that typically reaches a maximum adult size of approximately 2 inches (5 cm). This species displays sexual dimorphism, with males often being slightly smaller and exhibiting more vibrant coloration compared to females. A defining morphological feature is the prominent dark 'heart'-shaped spot located on the midflank, just posterior to the gill cover, which serves as a key identification marker. The body is generally translucent silver, and the fins may exhibit subtle red or orange tinting, particularly during breeding periods. The Black Heart Tetra possesses a well-developed lateral line system, which aids in detecting vibrations in the water, and its dentition is adapted for an omnivorous diet, featuring small, conical teeth suitable for grazing on both plant matter and small invertebrates. Additionally, the species has an adipose fin, which is characteristic of many members of the Characidae family, enhancing its hydrodynamic efficiency.
Behavior & temperament
The Black Heart Tetra is a social fish that thrives in small to medium-sized groups, exhibiting a schooling behavior that enhances its safety from predators. It typically occupies the mid to upper levels of the water column in its natural habitat, which consists of slow-moving blackwater streams and flooded forests in South America. During breeding, the species engages in a form of egg scattering, where females release eggs among vegetation, and males fertilize them externally. This species is generally peaceful and exhibits a mild temperament, making it suitable for community tanks, although it may display slight territoriality during breeding periods.
Diet & feeding
In the wild, the Black Heart Tetra is an omnivore, feeding on a varied diet that includes small invertebrates, plant matter, and detritus. In captivity, it requires 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.
