10 Popular Goldfish Breeds in Singapore [With FAQs]

Goldfish, celebrated for their rich colours and intricate patterns, hold a special place in the hearts of aquarium enthusiasts worldwide. Setting up a new aquarium or enriching your current aquatic collection requires a deep dive into the myriad types of goldfish available. From the swift Comet to the elegant Oranda, each breed presents its own set of unique traits and care needs.

This guide shines a spotlight on various goldfish breeds, detailing their characteristics, lifespans, and the ideal conditions for their care. Whether you’re an experienced fishkeeper or just beginning your aquarium adventure, embark on a journey with us through the fascinating world of goldfish breeds.


Tip!
Goldfish thrive in spacious environments that mimic their natural habitat, necessitating a well-filtered tank over the restrictive confines of a bowl. As temperate creatures, they adapt well to environments sans heaters, flourishing in large aquariums that offer ample swimming space. Cohabitation with other goldfish can provide companionship, though it’s crucial to select fish tank accessories that pose no risk of entrapment or injury.

For goldfish with elongated bodies and devoid of protruding eyes or double fins, an outdoor pond setting alongside koi can make for a harmonious dwelling.

1. Oranda Goldfish

Oranda Goldfish

The Oranda Goldfish shares the characteristic double tail feature with the Fantail variety, setting itself apart with the distinctive wen atop its head. This benign skin tissue growth, while normally harmless, can become overly enlarged due to dietary mismanagement or genetic factors. Should the wen grow excessively, professional intervention by a veterinarian is necessary to trim it back. 

It’s crucial to avoid trimming it on your own at home. Improper handling could result in serious harm to the fish’s sensitive eye tissue, potentially leading to blindness.

Lifespan: 15 to 25 years 
Length: 8 to 12 inches
Behaviour and temperament: Their serene temperament suits community tanks, allowing them to coexist well with other peaceful species.

2. Comet Goldfish

Comet Goldfish

The Comet Goldfish is easily recognised by its long, streamlined body and vibrant colour palette, ranging from white and gold to red. This breed is known for its rapid growth and considerable size, making it well-suited for spacious indoor aquariums and outdoor ponds.

Care should be taken to provide ample swimming space to accommodate their growth and active swimming habits.

Lifespan: 5 to 14 years
Length: up to 12 inches
Behaviour and temperament: Known for their adaptability, Comets thrive in diverse environments and mix well in a community setting with similar-sized, non-aggressive fish.

3. Shubunkin Goldfish

Shubunkin Goldfish

The Shubunkin Goldfish, a close relative of the Comet, distinguishes itself with a striking calico pattern, featuring a blend of black, red, white, and blue hues. Their elongated body and fins make them a captivating addition to both indoor tanks and garden ponds.

This breed’s visual appeal is matched by its resilience and ease of care.

Lifespan: up to 15 years
Length: up to 12 inches
Behaviour and temperament: Shubunkins are peaceful and blend seamlessly into community tanks, sharing space amicably with other non-aggressive fish.


Fun fact!
When provided with a spacious pond or tank, Shubunkin goldfish can grow to sizes of 12 to 14 inches, with some even reaching over 18 inches!

4. Ranchu Goldfish

Ranchu Goldfish

The Ranchu Goldfish, with its egg-shaped body and absence of a dorsal fin, is a cherished breed among goldfish enthusiasts. Often referred to as the “king of goldfish” in Japan, its unique appearance requires a bit more care, particularly in selecting a tank that accommodates its swimming style. 

Ranchus are best enjoyed in a well-set-up indoor aquarium where their distinctive silhouette can be appreciated.

Lifespan: 10 to 15 years
Length: 5 to 8 inches
Behaviour and temperament: they’re not suited for mixed-species tanks. Their well-being can be compromised by bullying, fin nipping, or competition for food when housed with faster, slender-bodied fish. They thrive in environments with similarly slow-moving, similarly sized goldfish, minimizing competition and the risk of fin damage.

5. Fantail Goldfish

Fantail Goldfish

Characterised by its double-tail fin and medium-to-short body, the Fantail goldfish presents a distinctive profile. This breed, with its variety of colours and graceful swimming, is best kept in indoor aquariums due to its slower swimming speed and vulnerability in outdoor settings.

Fantails are a classic choice for those seeking elegance and tranquillity in their aquarium.

Lifespan: 5 to 8 years
Length: 6 to 8 inches
Behaviour and temperament: Fantail goldfish are best housed alone or with their kind, rather than in a community tank with different fish species.

6. Ryukin Goldfish

Ryukin Goldfish

The Ryukin, with its short body and prominent hump at the shoulder, is a standout breed known for its vivid colouration and compact shape. Despite their less vigorous swimming ability, Ryukins command attention in any tank with their bold appearance and dynamic colour patterns.

Their unique physique does not hinder their compatibility with other peaceful tank mates.

Lifespan: 10 to 15 years
Length: 6 to 10 inches
Behaviour and temperament: Ryukin goldfish thrive in social settings, showing their happiest behaviours in groups. While they can be kept solo, their vibrant and active nature is more pronounced when they share their space with other fish.

7. Bubble Eye Goldfish

Bubble Eye Goldfish

Bubble Eye Goldfish are instantly recognisable by their large, fluid-filled sacs beneath their eyes, adding a unique level of intrigue to the aquarium. Due to their delicate sacs, they require an environment free of sharp edges and decorations. Their gentle swimming and distinctive look make them a focal point in any peaceful tank setup.

Lifespan: 10 to 15 years
Length: up to 5 inches
Behaviour and temperament: Bubble Eyes are peaceful and suited for calm community tanks, though care should be taken to ensure the safety of their delicate eye sacs.

8. Black Moor Goldfish

Black Moor Goldfish

Renowned for their large, telescope-like eyes and short, rounded bodies, Black Moor Goldfish offer a unique aesthetic with their deep black hues. These fish require special care to protect their delicate eyes from injury, necessitating a tank free from sharp or abrasive decorations.

Their distinct appearance adds a touch of mystery and elegance to any aquarium.

Lifespan: 10 to 15 years
Length: 4 to 8 inches
Behaviour and temperament: Despite their striking looks, Moors are gentle and can be housed with other peaceful fish, making them perfect for a serene tank environment.


Tip!
It’s important to note that they should not be kept with fish small enough to fit into their mouths. Like many goldfish, Black Moors can be opportunistic feeders, so pairing them with significantly smaller fish could lead to unintended consequences.

By selecting tank mates of a similar size, you can maintain a harmonious aquarium setting for these beautiful fish.

9. Veiltail Goldfish

Veiltail Goldfish

Veiltail Goldfish are known for their long, flowing tails and elegant swimming movements. This breed is highly prized for its beauty and the graceful manner in which it moves through the water.

 Veiltails are best kept in tanks where their fins can freely flow without the risk of snagging, making them a stunning addition to any aquarium.

Lifespan: 10 to 15 years
Length: 7 inches
Behaviour and temperament: Their peaceful nature makes Veiltails excellent community fish, though their slower speed and long fins mean they should be paired with gentle tank mates like Celestial Eye Goldfish. 

10. Celestial Eye Goldfish

Celestial Eye Goldfish

Celestial Eye Goldfish, with their upward-gazing eyes, offer a unique aesthetic among goldfish breeds. Their distinctive eye placement requires some accommodations to ensure they can feed effectively. Celestials add a curious and engaging aspect to any tank, captivating onlookers with their unusual appearance.

Lifespan: 10 to 15 years
Length: 5 to 6 inches
Behaviour and temperament: Despite their unique look, Celestials are peaceful and can be part of a community tank with other non-aggressive fish, provided the environment caters to their needs.

Keeping a Goldfish in Singapore

Before introducing any new goldfish to your tank or pond, adhering to a quarantine period is crucial. This preventative measure is essential to protect the health of your aquatic ecosystem and prevent disease transmission. 

Additionally, selecting appropriate tank accessories, particularly a robust filtration system, plays a pivotal role in creating a clean and supportive environment for your goldfish. 

Diet is also important; feeding your goldfish high-quality fish food specifically formulated for their needs is vital for their health and vibrancy. By providing the right care, focusing on their environmental needs, and ensuring proper nutrition, your goldfish are set to flourish, enhancing the beauty and vitality of your home aquarium or pond.

FAQs About Goldfish Breeds

The Black or Red Moor goldfish, often referred to as telescope eye goldfish, captivate many with their unique appearance. Characterised by their compact bodies and notably protruding eyes, these goldfish exude a distinctive charm that many find irresistibly cute.

Goldfish can survive in environments without an air pump, but this setup is far from ideal and can compromise their health and longevity. An air pump is instrumental in ensuring the water is well-oxygenated, providing the necessary oxygen levels for goldfish to thrive.

Mixing goldfish with other fish species is possible but requires careful consideration. Since goldfish prefer cooler water temperatures, ranging from 15-21°C, they are not suitable companions for tropical species like Betta fish, which thrive in warmer conditions. Compatibility and environmental needs should guide your choice of tank mates.

Generally, goldfish exhibit a peaceful demeanour and are not prone to aggression. Nevertheless, certain situations, such as competition for territory or mates among males, might trigger aggressive behaviours. Ensuring ample space and a well-managed tank can help minimise these occurrences.
