Blood Glass Fin Tetra L – Large Transparent Community Fish

Blood Glass Fin Tetra L is a beautiful and eye-catching variant of the Glass Bloodfin Tetra (Prionobrama filigera), known for its semi-transparent body, shimmering silver tones, and subtle red accents on the fins. The “L” size indicates larger, more mature specimens that display fuller bodies and more visible coloration.

This species is native to South American river systems, where it inhabits clear, slow-moving waters. Its unique “glass-like” transparency allows light to pass through parts of its body, creating a delicate and almost glowing appearance in well-lit aquariums.

When kept in groups, Blood Glass Fin Tetras exhibit active schooling behavior, moving gracefully through the mid-water level. Their subtle beauty makes them especially appealing in planted aquariums and aquascapes, where their reflective bodies contrast beautifully with greenery and natural décor.
