Glass Bloodfin Tetra

Aphyocharax anisitsi, the Glass Bloodfin Tetra, is native to the Paraná River basin in Argentina and is one of the hardiest and most cold-tolerant tetras available.

Feeding: Accepts virtually all foods — flake, pellets, frozen and live invertebrates. Behaviour: Peaceful schooling species; keep 8+; surface-to-mid-water activity. Compatibility: Excellent community fish; compatible with almost any similarly sized peaceful species.
