Care Tips for Butterfly Telescope Goldfish

Proper care is essential for maintaining the health and well-being of your Butterfly Telescope goldfish. By following these care tips, you can create a comfortable and thriving environment for your aquatic friends.

Tank Setup:

To provide adequate space for your Butterfly Telescope goldfish, it is recommended to have a tank size of at least 10 gallons per fish. A rectangular tank is the best choice, as it offers more swimming space. Ensure that the tank is properly cycled before introducing your goldfish. Additionally, consider the following:

  • Keep the water temperature between 65o and 72o Fahrenheit to mimic their natural habitat.
  • Maintain a pH level between 6.0 and 8.0 and water hardness between 5 and 19 dGH.
  • Install a strong filtration system to handle the high waste production of goldfish and keep the water clean.
  • Perform regular water changes and tank cleaning to prevent the buildup of harmful chemicals and maintain water quality.
  • Decorate the tank with items that are safe for your goldfish, avoiding sharp edges or objects that could damage their delicate fins or eyes.

Goldfish Diet:

Feeding your Butterfly Telescope goldfish a balanced diet is crucial for their overall health and vitality. Ensure the following:

  • Offer a varied diet that includes high-quality goldfish pellets, flakes, and frozen or live foods.
  • Feed your goldfish small portions multiple times a day, adjusting the amount based on their size and activity level. Avoid overfeeding, as it can lead to obesity and other health problems.
  • Monitor your goldfish during feeding to ensure they are consuming their food and remove any uneaten food to maintain water quality.

Tank Mates:

When choosing tank mates for your Butterfly Telescope goldfish, consider their compatibility to prevent aggression or stressful interactions. Opt for other fancy goldfish varieties that have a similar swimming speed and temperament. Slow-moving, non-aggressive species like the Bubble Eye, Celestial Eye, or Ranchu are good choices.
