Bloodfin Tetras (Aphyocharax anisitsi) originate in South America, specifically Argentina and Rio Parana. Their natural habitat is commonly shaded rivers and streams, with hanging vegetation and floaty greens. Being schooling fish, they're often found in groups and prefer the upper to mid-layers of water. They are only 2 ¼ inches, slim Aphyocharax anisitsi or Bloodfin Tetra by its common name belongs to the Characidae family or Characins. They were officially described by Eigenmann and Kennedy in 1903. Aphocharax means small charax, where charax means pointed pole, the species name refers to the small pointed teeth. The species name is a reference to Dr. J.D. Anisits. Bloodfin tetra tank requirements. Bloodfin tetras are a schooling fish that need enough space to the group and swim together. These fish will do best in a school of at least 6-8, with more being even better if space allows. Due to their schooling habits, a minimum tank size of 20 gallons (76 L) is recommended. Adults swim mainly in the upper and middle water layers. Feed on worms, small insects and crustaceans (Ref. 5723).Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 60 cm (Ref. 51150).Mature males always with gill glands and hooks in the anal fin ray (Ref. 58431). A. anisitsi has an olfactory rosette with an arrow-shaped arrangement, with differences in length between the anterior and posterior lamellae. In the olfactory epithelium, three types of olfactory receptor neurons were identified using histology and confirmed by immunohistochemistry, that is, ciliated olfactory receptor neurons in the basal region of the epithelium, microvillar olfactory Identification: Géry (1977) discussed the genus and provided a key (probably outdated). The genus Aphyocharax contains at least 10 species, all of which share the same common name: bloodfin tetras (Géry 1977). Size: 4-5.5 cm TL (Lima 2003) Native Range: Tropical America.
