Long-finned Glass Tetra Care Guide
Xenagoniates bondi · Freshwater Fish
What Long-finned Glass Tetra look like
The Long-finned Glass Tetra (Xenagoniates bondi) exhibits a strikingly transparent, laterally compressed body that can reach a maximum adult size of approximately 5 inches. This species is characterized by its elongated, filamentous fin extensions, particularly prominent in the dorsal and caudal fins, which contribute to its ethereal appearance. The transparency of the body allows for the visibility of internal structures, a unique adaptation that enhances its camouflage in natural habitats. Sexual dimorphism is subtle, with females generally being slightly larger and rounder than males, particularly during breeding periods. Defensive adaptations include its transparent body which aids in evasion from predators, and the presence of a lateral line system that assists in detecting water movements. The overall morphology is further accentuated by the delicate, long fins that sway gracefully in the water, enhancing its aesthetic appeal.
Behavior & temperament
In terms of behavior, the Long-finned Glass Tetra is a gregarious species that thrives in schools, exhibiting a strong social hierarchy where individuals establish dominance through subtle displays of fin extension and body posturing. They predominantly inhabit the mid to upper water column, where they engage in active swimming and foraging. Breeding behavior is characterized by egg scattering, with females releasing eggs in open water while males fertilize them externally. This species is generally peaceful, exhibiting low aggression levels, making them suitable for community tanks. Their social nature encourages them to remain in groups, which helps reduce stress and promotes natural behaviors.
Diet & feeding
In the wild, the Long-finned Glass Tetra is an omnivorous feeder, consuming 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 brine shrimp and daphnia to maintain their health and vibrancy.
