Let’s get you ready to become a confident and happy celestial eye keeper!
What Makes the Celestial Eye Goldfish So Special?
Before we dive into the “how-to,” let’s take a moment to appreciate what makes this fish so captivating. The celestial eye is a “fancy goldfish,” meaning it’s been selectively bred over centuries from the common carp, just like Orandas, Ryukins, and Ranchus.
Their most defining feature, of course, is their eyes. The pupils are permanently turned upwards, housed in large, protruding sockets. This unique trait means they have very poor forward and downward vision, a crucial fact that will inform every aspect of their care.
Another key feature is the absence of a dorsal fin, which gives them a smooth, egg-shaped body and a slightly wobbly, endearing swimming style. They are not powerful swimmers, making them gentle, slow-moving inhabitants of any tank they’re in.
The Benefits of Celestial Eye Goldfish Keeping
Why choose a celestial eye? Beyond their unique look, there are several wonderful benefits of celestial eye goldfish that make them a joy to keep:
- Peaceful Temperament: They are incredibly docile and non-aggressive, making them a calming presence in the aquarium.
- Unique Personality: Their clumsy swimming and curious nature give them a ton of personality. You’ll quickly learn their individual quirks!
- Relatively Hardy: Despite their delicate appearance, they are quite hardy when provided with the correct environment.
- A True Conversation Starter: Be prepared for guests to be absolutely mesmerized by your star-gazing swimmers!
Your Celestial Eye Goldfish Care Guide: The Perfect Tank Setup
Creating the right environment is the most important step in ensuring a long, healthy life for your fish. Because of their poor eyesight and delicate bodies, their home needs to be a safe space, free from hazards. Here are the celestial eye goldfish best practices for tank setup.
Tank Size and Shape
Goldfish produce a lot of waste, so bigger is always better. For a single celestial eye, a 20-gallon (75-liter) tank is the absolute minimum. For each additional fancy goldfish, you should add at least 10 gallons (40 liters).
A long, shallow tank is preferable to a tall, deep one. This provides more surface area for oxygen exchange and makes it easier for these clumsy swimmers to reach the surface if needed.
Filtration and Water Parameters
A high-quality filter is non-negotiable. Because they are messy, you need a filter rated for a slightly larger tank than you have. A hang-on-back (HOB) or canister filter works great. Crucially, make sure the filter outflow isn’t too strong. A powerful current will toss these poor swimmers around. You can baffle the output with a sponge if it’s too aggressive.
Keep these water parameters stable:
- Temperature: 65-75°F (18-24°C)
- pH: 6.5 – 7.5
- Ammonia: 0 ppm
- Nitrite: 0 ppm
- Nitrate: Below 40 ppm (ideally below 20 ppm)
Regular water changes are key. A 25-30% water change every week is a great routine to stick to. This keeps the nitrates low and the water fresh.
Substrate and Decorations: Safety First!
This is one of the most important celestial eye goldfish tips I can give you. Their upward-gazing eyes are extremely vulnerable to injury from below. They simply can’t see sharp objects in their path.
Your tank decor must be completely smooth. Here are some safe choices:
- Substrate: A bare-bottom tank is the safest option. If you prefer substrate, use very fine, smooth sand or large, perfectly smooth river rocks that are too big to be swallowed. Avoid gravel at all costs, as it can injure their eyes and become a choking hazard.
- Decorations: Choose rounded, smooth decorations. Avoid anything with sharp edges, points, or tight crevices where they could get stuck.
- Plants: Live plants are fantastic! They help with water quality and provide soft surfaces. Anubias, Java Fern, and Marimo Moss Balls are excellent choices. If you use artificial plants, only use silk plants, never plastic ones, which can have sharp edges.
Feeding Your Star-Gazers: Best Practices for Health and Safety
Figuring out how to celestial eye goldfish feeding works is a fun challenge. Their upward eyes and slow nature mean they can be easily outcompeted for food and may struggle to find it. Don’t worry, it’s easy once you get the hang of it!
What to Feed Them
A varied diet is essential for a healthy goldfish. The best foundation is a high-quality, slow-sinking pellet or gel food specifically designed for fancy goldfish. Sinking food is crucial because it prevents them from gulping air at the surface, which can lead to buoyancy problems.
Supplement their diet with treats like:
- Blanched vegetables (deshelled peas, zucchini, spinach)
- Bloodworms (frozen or freeze-dried)
- Brine shrimp
- Daphnia
Always pre-soak dry foods like pellets and freeze-dried treats in a bit of tank water for a few minutes before feeding. This helps prevent bloating and digestive issues.
Pro Feeding Tips for Celestial Eyes
Because they can’t see down, you need to help them find their food. Here are a few tricks that work wonders:
- Use a Feeding Dish: Place a small, smooth glass or ceramic dish on the substrate. Consistently drop the food into this dish during feeding time. Your fish will quickly learn where to go for their meals!
- Hand Feeding: This is a wonderful way to bond with your fish. Hold the food near their mouth, and they will gently take it from your fingers. It ensures they eat and builds trust.
- Train with a Signal: Gently tap on the glass in the same spot right before you add food. This auditory cue will help them know it’s feeding time and where to find the meal.
Feed them small amounts once or twice a day. Only give them what they can consume in about a minute to prevent overfeeding and keep the water clean.
Choosing Peaceful Companions: The Best Tank Mates
Celestial eye goldfish are lovers, not fighters. They are slow, have poor vision, and cannot compete with fast or aggressive fish. Choosing the right tank mates is essential for their well-being.
The best tank mates are other similarly handicapped fancy goldfish. This ensures everyone has a fair chance at food and no one gets bullied. Great companions include:
- Other Celestial Eyes
- Bubble Eye Goldfish
- Telescope Eye Goldfish
- Lionhead and Ranchu Goldfish
Fish to strictly avoid include:
- Fast-swimming single-tailed goldfish like Comets or Shubunkins. They will eat all the food before the celestials even know it’s there.
- Fin-nippers like some types of barbs or tetras.
- Any aggressive or territorial fish, such as cichlids.
- Small fish that could be eaten by the goldfish.
When in doubt, a species-only tank is the safest and often most beautiful option for these special fish.
Common Problems with Celestial Eye Goldfish (And How to Solve Them)
Even with the best care, you might run into issues. Being able to spot the common problems with celestial eye goldfish early is key to fixing them quickly.
Eye Injuries or Infections
This is the most common ailment specific to this breed. Their eyes can get scratched on sharp decor or become cloudy due to poor water quality.
- Prevention: Follow the decor safety rules above! Keep your water pristine with regular changes.
- Treatment: If you notice an injury or cloudiness, perform an immediate water change. If it looks infected (red, swollen, or fuzzy), a quarantine tank and veterinarian-prescribed antibacterial medication may be necessary.
Swim Bladder Disease
This condition affects a fish’s buoyancy, causing them to float uncontrollably or struggle to leave the bottom. It’s often caused by gulping air during feeding or poor diet.
- Prevention: Feed only sinking foods and pre-soak them. Incorporate blanched peas into their diet, as the fiber aids digestion.
- Treatment: Fast the fish for 2-3 days. Then, feed only blanched, deshelled peas for a few days. Raising the tank temperature slightly can also help with digestion.
Bacterial and Fungal Infections (Fin Rot, Ich)
These are common in all aquariums and are almost always a result of stress from poor water quality.
- Prevention: The number one prevention is maintaining clean, stable water conditions. A happy fish is a healthy fish.
- Treatment: Ich (white spots) can often be treated by slowly raising the temperature and using aquarium salt or specific medications. Fin rot (tattered, decaying fins) usually requires medicated treatment in a hospital tank.
Sustainable and Eco-Friendly Celestial Eye Goldfish Keeping
Being a responsible aquarist also means thinking about our impact. Practicing sustainable celestial eye goldfish keeping is easier than you think and benefits both your fish and the environment.
Here are some eco-friendly celestial eye goldfish tips:
- Source Fish Responsibly: Whenever possible, purchase your fish from reputable local breeders or stores that prioritize the health and ethical treatment of their animals. This reduces the stress of long-distance shipping and supports good practices.
- Conserve Water: When doing water changes, use the old aquarium water for your houseplants! It’s full of nitrogen and other nutrients that plants love. It’s a fantastic, free fertilizer.
- Use Live Plants: Live plants act as natural filters, consuming nitrates and improving water quality. This can reduce the frequency or volume of water changes needed over time.
- Energy-Efficient Equipment: When buying new equipment like lights or heaters, look for energy-efficient models. LED lighting, for example, uses far less electricity than older fluorescent bulbs.
