Apri l'appDescrizione
Prionobrama filigera, commonly known as the Glass Bloodfin Tetra, is a small, schooling freshwater fish belonging to the family Characidae. It is highly prized in the aquarium trade for its translucent body, which allows for the observation of its internal organs, and its striking red-orange fins. This species exhibits a slender, elongated body form, typical of many characins, and is generally peaceful, making it a suitable inhabitant for community aquariums.
Caratteristiche fisiche
- Forma del corpo
- elongated
- Colorazione
- The body is largely translucent, appearing silvery-clear, allowing internal organs to be visible. The caudal fin, and often the dorsal, anal, and pectoral fins, are a vibrant red to orange. A faint, iridescent lateral line may be present.
- Tipo di squame
- cycloid
- Posizione della bocca
- terminal
- Caratteristiche distintive
- Translucent body, Vibrant red-orange fins, especially the caudal fin, Slender, elongated body, Small adipose fin
- Pinna dorsale
- Single, relatively small dorsal fin located mid-body, often with a reddish tint.
- Pinna caudale
- Deeply forked caudal fin, typically bright red or orange, providing propulsion.
- Pinna pettorale
- Small, clear to reddish pectoral fins, used for maneuvering.
- Pinne distintive
- Presence of a small, fleshy adipose fin between the dorsal and caudal fins, characteristic of characins. Anal fin is relatively long, extending along the posterior ventral side.
Consigli per l'identificazione
Body Transparency
The most defining characteristic is its almost completely transparent body, through which the spine and some internal organs are visible. This distinguishes it from most other tetras.
Fin Coloration
Look for the bright red or orange coloration on the caudal fin, which is often the most intense, and sometimes on the other fins as well.
Body Shape
Its slender, elongated body shape is typical of many characins, but combined with the transparency and fin color, it's quite unique.
Schooling Behavior
In its natural habitat and in aquariums, it almost always forms tight schools, which can aid in identification.
Habitat
- Tipo di acqua
- freshwater
- Profondità
- Typically found in shallow to moderate depths, often near the surface or mid-water column.
- Ambiente
- Inhabits slow-moving rivers, streams, and floodplains, particularly in areas with dense vegetation, submerged roots, and leaf litter. Prefers clear to blackwater environments with soft, acidic water.
- Areale geografico
- Native to South America, primarily found in the Amazon River basin, including tributaries in Brazil, Peru, and Bolivia. Also reported in parts of the Orinoco River basin.

Fatti chiave
Living X-rayamazing
The extreme transparency of the Glass Bloodfin Tetra's body allows aquarists and scientists to observe its internal organs, including its beating heart and digestive tract, without dissection.
Schooling for Safetybehavior
In the wild, Prionobrama filigera forms large, cohesive schools. This behavior is a primary defense mechanism against predators, as it creates confusion and reduces the chance of any single individual being targeted.
Fin Regenerationinteresting
Like many characins, Glass Bloodfin Tetras have a remarkable ability to regenerate damaged fins, provided the damage is not too severe and water quality is maintained.
Indicator Speciesinteresting
Due to their preference for clean, well-oxygenated water, the presence of healthy populations of Glass Bloodfin Tetras can sometimes indicate good water quality in their natural habitats.

Specie simili
Red-eyed Tetra
Moenkhausia sanctaefilomenae
While also having red fins and a silvery body, the Red-eyed Tetra is not translucent and has a prominent red iris in its eye, which is absent in Prionobrama filigera.
Glass Catfish
Kryptopterus vitreolus
The Glass Catfish is also transparent but belongs to a different family (Siluridae), has a distinctly different body shape (more compressed, lacking a dorsal fin, and having long barbels), and is found in Southeast Asia, not South America.
Blind Cave Tetra
Astyanax mexicanus (cave morph)
While also somewhat translucent, the Blind Cave Tetra lacks eyes and pigmentation, a result of its cave-dwelling adaptation, and does not possess the vibrant red fins of Prionobrama filigera.
