Water Conditions:

• Water Temperature: The ideal water temperature for your aquarium should be between 22°C to 28°C (72°F to 82°F), which is suitable for most tropical fish. Use a reliable aquarium thermometer to monitor the temperature.

• pH Levels: Freshwater fish generally thrive in water with a pH level of 6.5 to 7.5. Regular water testing is important to maintain the right balance for your fish.

• Water Hardness: Soft to moderately hard water (3-12 dGH) is perfect for many freshwater species. It is recommended to test your water’s hardness regularly to ensure it matches your fish’s needs.

• Water Quality: Regular water changes (20-30% per week) and filter maintenance are essential to maintaining optimal water quality. Always use a water conditioner to remove chlorine or chloramine from tap water before adding it to your tank.

Tank Mates:

• The Resun 21L Starter Aquarium is ideal for small, peaceful fish species. These may include:
  • Betta Fish (1 per tank, as they are territorial)
  • Neon Tetras (5-6, as they thrive in small schools)
  • Guppies (4-5, as they are active and sociable)
  • Zebra Danios (3-4, as they are hardy and can adapt to various water conditions)
  • Corydoras Catfish (1-2, as they are bottom dwellers and help clean the tank)
  Avoid aggressive species such as large cichlids or fish that might harm smaller tank mates.

Feeding Habits:

• Fish in the Resun 21L aquarium should be fed a diet that matches their species. Most small freshwater fish thrive on high-quality flake food, pellets, or freeze-dried food. It is important not to overfeed your fish as this can lead to water contamination.
  • Frequency: Feed your fish once or twice daily, ensuring they consume the food within a few minutes. Remove any uneaten food promptly to avoid water pollution.
  • Variety: Supplement their diet with occasional treats like frozen or live brine shrimp, bloodworms, or daphnia. This variety will enhance their health and coloration.

Care and Maintenance:

• Regular Water Changes: To maintain a healthy tank environment, change 20-30% of the water every week. This helps in removing waste and replenishing beneficial minerals in the water.

• Filter Maintenance: Clean the filter media every 2-4 weeks, depending on the water quality and the amount of debris. Replace the filter cartridges as recommended by the manufacturer to ensure the system works efficiently.

• Tank Cleaning: Use an algae scraper or magnetic cleaner to remove algae from the tank walls. Clean decorations and substrate occasionally to ensure a clean and inviting environment for your fish.

The Resun 21L Starter Aquarium Fish Tank is an ideal choice for beginners looking to create a low-maintenance and beautiful aquatic home. With its LED lighting, efficient filtration, and compact design, it provides a great environment for a wide range of freshwater fish.
