The Red Rainbowfish (Glossolepis incisa), often sold as the Red Irian Rainbowfish or Salmon Red Rainbowfish, is a striking freshwater fish famous for its deep, vibrant crimson color. Native exclusively to Lake Sentani in West Papua, Indonesia, these active, schooling fish are a highly prized centerpiece species for medium to large community aquariums.

 Tank Setup & Behavior
  • Schooling Dynamics: They must be kept in groups of 5 or more (ideally balanced with one male to every two females). Keeping them in groups reduces aggression and stimulates the males to flash their brightest colors while competing for female attention.
  • Aquarium Decor: These fish look best against a dark substrate in a well-planted aquarium. Ensure you leave plenty of open swimming space in the center, as they are constant, rapid swimmers. 
  • Juvenile Drabness: Do not be discouraged if they look olive-brown or silver at the pet store. Rainbowfish juveniles are naturally plain and will only develop their signature blinding red coloration once they mature and settle into a stable environment. 
Gender Differences (Sexual Dimorphism)
  • Males: Bright, cherry-red bodies that grow a distinctively high, arched back as they age.
  • Females: Much more understated, featuring an olive-brown or brassy-silver body with smaller fins. [1, 2]
