aka: Lowe’s Tetra
Hyphessobrycon cf. loweae
Native to: The headwaters of the Xingu drainage, Mato Grosso, Brazil.
Size: Around 3-4cm/1.2-1.6\”, females a bit smaller.
Aquarium: Quite a peaceful tetra which mixes well with other fish when kept in a small group. Male Hyphessobrycon display their best colors and behavior when kept in mixed sex groups alongside plenty of females.
Diet: Bloodworms, Daphnia, Cyclops, flakes etc.
Sexing: These pretty characins are both sexual dichromatic and dimorphic, so they\’re easy to sex once mature. Both sexes turn yellow when adult, but the males have much more orange and red on their flanks and fins. Males are also bigger and have a flag dorsal fin. Their anal and pelvic fins are also longer and redder than those of the female.
Similar species: There are over 90 other fish in this genus. The rare H. heliacus, which was described from the nearby upper Tapajos in Mato Grosso, Brazil, in 2002 is the most likely to be confused with this fish. It also shares the big dorsal in males and the same yellowy sheen as loweae (see Moreira et al. 2002 to differentiate by a process of deduction). These are a rre tetra not usually for sale anywhere.
