Glass Bloodfin Tetra Care Guide
Prionobrama filigera · Freshwater Fish
What Glass Bloodfin Tetra look like
The Glass Bloodfin Tetra (Prionobrama filigera) exhibits a distinctive elongated, laterally compressed body that can reach a maximum adult size of approximately 5 cm (2 inches). Its most striking feature is its entirely transparent, glass-like integument, which provides an ethereal appearance, allowing for visibility of internal structures. The only notable pigmentation is found in the deeply bright red coloration of the caudal fin, which serves as a visual cue for conspecifics. Sexual dimorphism is subtle; males tend to display slightly more vibrant coloration in the tail and may exhibit a more streamlined body during breeding periods. Defensive adaptations include its transparency, which aids in evasion from predators, and the presence of a lateral line system that enhances its sensitivity to water movements. The species lacks an adipose fin, a characteristic feature of many Characidae, and possesses small, conical teeth adapted for an omnivorous diet.
Behavior & temperament
The Glass Bloodfin Tetra is a social species that thrives in small to medium-sized schools, exhibiting a hierarchical structure where dominant individuals often display more vibrant coloration and assertiveness. It typically occupies the mid to upper water column, favoring areas with ample vegetation for cover. Breeding behavior involves egg scattering, where females release eggs among plants, and males fertilize them externally. The species is generally peaceful, displaying a calm temperament; however, it can exhibit mild territoriality during breeding periods, particularly in confined spaces. This species is best kept in groups to promote natural behaviors and reduce stress.
Diet & feeding
In the wild, the Glass Bloodfin Tetra is an omnivore, feeding on small invertebrates, plant matter, and detritus. In captivity, it requires a varied diet that includes high-quality flake foods, live or frozen foods such as brine shrimp and daphnia, along with vegetable matter to ensure optimal health.
