Buying Guide: Key Purchase Considerations

  • Tank size and compatible species: For bottom dwellers like Kuhli Loach, ensure enough hiding spots and a soft substrate. For schooling fish like Neon Tetras or Guppies, plan for groups to reduce stress and encourage natural behavior.
  • Water parameters: Check temperature, pH, and hardness requirements. Guppies and tetras generally prefer stable, moderate ranges; bottom dwellers may tolerate slightly different conditions.
  • Shipping considerations: Shipping can be impacted by extreme temperatures. When ordering in adverse weather, be prepared with a stable acclimation plan and a quarantine period for new arrivals.
  • Life stage and health: Live shipments arrive best when sourced from brands that health-check and carefully select fish. Inspect upon arrival and acclimate gradually to reduce stress.
  • Diet and feeding: Most listed species are omnivores or small carnivores. Have sinking pellets, frozen foods, and bio-compatible flakes available to support natural feeding habits.
  • Tank setup and compatibility: Consider a planted tank, filter type, and community balance. Some species are peaceful but may be stressed by aggressive tank mates or overcrowding.
