• Water Conditions:
  • Temperature: Prefer cooler water between 65–75°F (18–24°C). Temperatures consistently above 77°F (25°C) can be harmful.
  • pH & Hardness: They thrive in hard, alkaline water with a pH between 7.0 and 8.0.
  • Filtration: Appreciate clean, well-oxygenated water with some flow to mimic their natural river habitats.
• Maintenance: Large weekly water changes (up to 60-80%) are recommended to keep the strain healthy and robust. 

• Trophotaenia: Developing fry are nourished by a specialized structure similar to a mammalian placenta, which can sometimes be seen attached to the young at birth.
• Fry Size: Females produce small broods (5–30 fry) every two months. The newborns are exceptionally large—around 0.6 to 0.75 inches—and can immediately eat crushed flakes or baby brine shrimp.
• Sperm Storage: They do not store sperm; a new mating is required for every brood
