Tank Size and Conditions

A 15-gallon tank or larger is recommended for a school of Glowlight Tetra but they will benefit from some more swimming room.

  1. Temperature: 72-80°F (22-27°C), ideal for their tropical nature.
  2. pH Level: 6.0 to 7.5, preferring slightly acidic to neutral water.
  3. Water Hardness: 4-10 dGH, indicating a preference for soft to moderately hard water.
  4. Water Quality: Like most fish, Glowlight Tetra require clean and well-oxygenated water. Regular water changes (about 25% per week) are recommended to maintain good water quality. It’s crucial to remove any chlorine or chloramine from tap water before adding it to the tank.
  5. Nitrate Levels: Keeping nitrate levels low is important, as high levels can be harmful. Aim to keep nitrates below 20 ppm.
  6. Ammonia and Nitrite Levels: Both ammonia and nitrite should always be at 0 ppm. Even small amounts of these can be toxic to fish.

It’s important to use a reliable aquarium test kit to regularly monitor these water parameters. Sudden changes in water conditions can stress or harm your fish, so any adjustments should be made gradually. Maintaining stable water conditions is key to the health and longevity of your Glowlight Tetra. 🌊
