(8) Leporius Affins

"leporius affins" is a common misspelling of Leporinus affinis,

a species of freshwater fish from the Amazon River basin, also known as the many-banded or headstander leporinus. It is known for its torpedo-shaped body, distinctive stripes, and an active, sometimes territorial, temperament.

• Coloration: When mature, they have a yellow body with nine thick, black vertical stripes. Young leporinus may have fewer stripes, which will split and increase in number as they grow older.
• Body: They have an elongated, torpedo-shaped body, with a mouth and teeth adapted for their diet.
• Size:
  
  
  L. affinis can grow up to 10–12 inches (25–30 cm) in length. 

• Tank size: A minimum of a 75-gallon tank is recommended for a single specimen, with a larger tank being necessary for a group. The tank should be well-oxygenated and have a strong water current to mimic their natural river habitat.
• Water parameters: They are adaptable but prefer clean, stable water conditions.
  • Temperature:
    
    
    73–82°F (23–28°C).
  • pH: 5.5–7.7.
• Aquascaping: Provide plenty of open swimming space, along with driftwood and rocks for shelter. Live plants will likely be eaten, so artificial plants can be used instead.
• Lid:
  
  
  A tight-fitting and heavy lid is essential, as leporinus are known for their jumping ability. 

• Omnivorous: Though they have a strong preference for vegetable matter, leporinus are omnivores and should be fed a varied diet.
• Foods: Include high-quality pellets, spirulina flakes, and fresh vegetables like cucumber or peas. Supplement with meaty foods like bloodworms and brine shrimp. 

• Temperament: While generally peaceful, they can be territorial and aggressive toward smaller fish and their own species. They are also known to be fin-nippers.
• Schooling behavior: In the wild, they live in large groups. To minimize aggression in a home aquarium, it is best to either keep a single specimen or a larger group of 8 or more, as this diffuses any hostility.
• Compatible tank mates:
  
  
  • Larger, robust fish: Non-aggressive cichlids, large tetras, and robust catfish.
• Incompatible tank mates:
  • Smaller or slow-moving fish:
    
    
    Anything small enough to be eaten or with long, flowing fins.
