Livebearer with small broods. Priapella keepers stress flying insects (e.g. fruit flies) as an aid to breeding, a strong-filtered, well-lit tank, and a shoal.
One male to 3-4 females.
Planted 100 L tank with hard, warm water and gentle flow.
Warm, hard water and a varied diet.
Only 5-20 young per brood after about 28 days gestation.
Feed baby brine shrimp and finely crushed flake.
A small southern Mexican livebearer with bright blue eyes that lives in shoals in flowing streams and leaps to catch flying insects.
Mexican ichthyologists José Álvarez and Jorge Carranza described this livebearer in 1952. Its bright blue eyes make it a charming fish for community tanks.
First described by José Álvarez & Jorge Carranza in 1952.
