Tamasaba Goldfish Species Profile and Identification

The Tamasaba Goldfish is an intriguing specimen, known also by names such as SabaoMackerel tail, or Yamagata Goldfish. It hails from the Yamagata Prefecture in Northern Japan with a captivating appearance which is rarely seen in other goldfish species.

  • Tamasabas are generally large in size, reaching up to 10-12 inches (30 cm) in length.
  • Lifespan is about 10-15 years in proper conditions, however, the Guinness Book lists 43 years as the record.
  • Prominent colors are solid red and white, though a deep red variant is also observed.

The Tamasaba goldfish resembles the Ryukin in body shape, but it’s easily identifiable by its long, flowing, and single tail that parallels the mackerel. Its large body and single tail give it a distinctive presence in any pond or aquarium. This goldfish is an ornamental pet and is bred both naturally and artificially.

Despite having similarities, Tamasabas often get confused with Sabao Goldfish. It’s essential to note that these are two separate kinds of Goldfish species. Know that the vibrancy of a Tamasaba’s colors and the health of its single tail fin are key identifiers for this particular species.

Maintaining the perfect environment and diet is crucial for the Tamasabas to thrive. They tolerate almost any weather condition and have an omnivorous diet.

Best kept in a water temperature between 50°F – 82°F (10-28 ℃), and a pH range of 6.0 to 8.3. It’s their sturdy nature that makes them compatible with Koi and most pond fish species, giving them worldwide availability.

Tamasaba Goldfish Supplies

Purchasing the correct supplies is crucial to your Tamasaba Goldfish’s health and well-being. Let’s discuss the essentials.

Tamasaba Goldfish Tank Setup

Before introducing a Tamasaba Goldfish to your home, preparing the proper tank setup is crucial. The tank size is critical – a large, spacious tank is required. A single Tamasaba would require a minimum of 50 gallons (around 190 liters) because of their large size and active nature.

They’re known to grow up to 10-12 inches (30 cm) long, which means they need a lot of room to swim around. Avoid overcrowded conditions as they not only cause high stress levels, but also lead to a higher risk of disease.

  • Tank Type: A tank with a rectangular or rounded shape would be perfect. Rectangular tanks are preferred as they offer more swimming space.
  • Substrate: Use small to medium gravel. The Tamasaba goldfish enjoys rummaging and foraging through the substrate.
  • Tank décor: Keep décor minimal to provide sufficient swimming space. Ensure that all decorations have no sharp edges that could harm the fish. A few suitable options include smooth rocks, live plants, and driftwood.
  • Lighting: The tank should be lit for 8-12 hours a day. Too much exposure to light can cause stress for the fish.

The importance of filtration cannot be overstated. Tamasaba goldfish, like other goldfish species, produce a good amount of waste and thus need good filtration. Ideally, a filter with both mechanical and biological filtration capabilities would be best. Furthermore, the filter should be able to handle the high water volume that you will be adding to the tank.

A spacious tank, proper substrate and décor, sufficient lighting, and robust filtration are key to creating an ideal living space for a Tamasaba goldfish.

Tamasaba Goldfish Water Requirements

Your Tamasaba Goldfish will thrive in a variety of water conditions which increases their popularity as pet fish. The essential water parameters should not be neglected. Ensure that your goldfish has the right conditions for optimal growth.

  • Temperature: The ideal temperature range for Tamasaba goldfish is between 50°F and 82°F (10-28℃). Aim for consistency as rapid temperature changes can stress your goldfish.
  • pH Level: The pH level of your goldfish tank should be maintained between 6.0-8.3. Sudden changes in pH levels can prove detrimental.
  • Water Hardness: Aim for a water hardness between 5° to 25° dH. Tamasaba goldfish can tolerate different hardness levels, but consistency is crucial.

Regular water changes can maintain these conditions. Aim to change about 10-20% of the tank water weekly. This will help to keep water parameters stable and avoid the buildup of harmful substances.

Regardless of the conditions, remember to acclimate your Tamasaba Goldfish to any new water environment. This gradual introduction allows your fish to comfortably adjust to changes in temperature, pH and water hardness. Without it, your Tamasaba may experience stress and potential health problems.

Your Tamasaba’s ability to withstand varying conditions is a bonus. But still strive for stability in your tank. This will ensure your goldfish lives a long and healthy life.

Tamasaba Goldfish Diet and Feeding

Feeding your Tamasaba Goldfish appropriately is crucial to its health. One key fact to remember is that Tamasabas are omnivorous, they gladly consume both plant-based and meat-based food.

Basic Diet

A quality goldfish pellet or flake food specifically designed for goldfish should form the basis of their diet. However, don’t stop at this. Variety is important.

  • Make sure to incorporate live foods into their diet such as brine shrimp, daphnia, and bloodworms.
  • You can also provide them with vegetable supplements such as lettuce, boiled peas, and spinach.

Feeding Routine

A good rule of thumb is to feed them twice a day – once in the morning and once in the evening.

  • Tamasabas should be fed in small amounts.
  • Only feed them what they can consume within two to three minutes.
  • Overfeeding can lead to obesity and other health issues.

Hunger Signs

Tamasaba Goldfish can be greedy eaters and might constantly appear hungry. However, do not overindulge their appetite. Stick diligently to the feeding routine and amount discussed above.


Abrupt changes in diet can stress your Tamasaba. Any transition should be gradual, for example, while introducing new foods.

A balanced diet and proper feeding routine is key. Remember, quality over quantity, and provide variety wherever possible. Happy feeding!

Tamasaba Goldfish Care Schedule

Adhering to a regular care schedule is paramount to your Tamasaba goldfish’s health and longevity. The following care schedule will guide you for the daily, weekly, and monthly tasks:

Daily Tasks

  • Feeding: Goldfish are omnivorous and need feeding two to three times daily. The portions should be enough for them to finish in two minutes.
  • Observation: Carefully observing your Tamasaba daily can hint at potential health issues. Look out for changes in eating behavior, swimming patterns, and physical appearance.

Weekly Tasks

  • Partial Water Changes: An important part of optimal tank health involves changing 10-20% of the tank’s water every week. This helps to maintain the water’s chemical balance.

Monthly Tasks

  • Comprehensive Tank Cleaning: Every month, ensure an in-depth clean of the whole tank. However, be cautious not to disrupt the biological filtration.
  • Test Water Chemistry: Regularly (at least monthly) test the water’s pH, hardness, nitrate, and ammonia levels. These elements can greatly impact your Tamasaba’s health if not properly regulated.

Following this care schedule will go a long way in keeping your Tamasaba goldfish healthy. Remember, consistency is key.

Tamasaba Goldfish Health Problems

Like other goldfish varieties, Tamasabas can suffer from common fish illnesses. They can be prone to fungal and bacterial infections, which can lead to problems like fin rot, dropsy, and white spot disease.

  • Fin Rot: This is a bacterial infection that causes the fins of your Tamasaba Goldfish to decay. It’s easy to spot as you’ll see shredding and discoloration on the fin edges. To tackle this, keep your tank clean and treat it with a quality fin rot medication.
  • Dropsy: This is a bacterial disease that causes the fish to bloat and scales to protrude. It’s often a symptom of poor water conditions, so regular water changes and maintaining ideal water parameters can prevent this.
  • White Spot Disease: Also known as Ich, this is a parasitic infection that appears as white spots on the goldfish’s body. Quarantine the infected fish and treat all tank inhabiting fish with a trusted Ich treatment medication.

Regularly check on your Tamasabas and observe their behavior, appearance, and eating patterns. Any changes may be the first sign of a health problem. Besides treating health problems, prevention is always more effective. So, keep the water clean, feed a balanced diet, and provide a stress-free environment.

Remember, your Tamasabas can live for many years with the right care and attention. Thus, being vigilant about their health will provide a safer habitat. Although they’re hardy by nature, they still require regular maintenance to keep them in good health.

Tamasaba Goldfish Tank Mates

One of the most rewarding parts of keeping a Tamasaba goldfish is the ability to mingle them with a variety of other aquatic species. However, compatibility should be at the forefront of your selection process. Some critical points to consider when choosing tank mates for your Tamasaba goldfish:

  • Size and Temperament: Goldfish are generally peaceful and could be bullied by more aggressive or large fish species. Hence, avoid predatory fish such as Arowanas or Cichlids.
  • Environmental Requirements: Tamasaba goldfish can cope with a wide range of temperatures. However, it’s crucial to pair them with species that have similar water condition needs. Koi and most other pond fish species, for instance, are harmonious tank buddies.

Good Tank Mates:

  • Ryukin GoldfishFantail GoldfishComet Goldfish
  • Plecostomus
  • Bristlenose Catfish

Poor Tank Mates:

  • Tropical Fish
  • Cichlids
  • Arowanas

Finally, goldfish are noted for their voracious appetite and could potentially consume smaller fish. Adding tank mates of equivalent size will prevent any tragic accidents. Tamasaba’s low aggression levels and tendency to graze rather than ruthlessly hunt make them ideal for peaceful, cohabitational setups.

But always remember – the needs and well-being of your Tamasaba should be the top priority when introducing any new tank mates.

Tamasaba Goldfish Breeding

Breeding Tamasaba goldfish is a meticulous yet rewarding process. Given the right conditions, these goldfish species will breed on their own, similar to many fish species. It’s important to note that Tamasaba goldfish breed through both artificial and natural methods.

To prepare for breeding, ensure a well-balanced diet for your goldfish. High-protein foods like brine shrimps and Daphnia will improve their chances of breeding.

  • Temperature: It plays a role in triggering spawning in Tamasaba goldfish. Increasing the water temperature to 68°F – 74°F (20°C – 23°C) for a couple of weeks before breeding can encourage spawning.

Also, make sure that you have a spawning mop or plants in the tank. The female Tamasaba goldfish will deposit her eggs on these. Once the eggs are fertilized, they will hatch in about 4-7 days.

It’s recommended to remove the parent fish from the tank after spawning to prevent them from eating the eggs. The newborn fry should be fed with infusoria or special fry food until they are large enough to eat regular goldfish food.

Observe and separate any intensely colored fry. They will grow into the iconic red and white Tamasaba goldfish. Although breeding Tamasaba goldfish can be an intricate process, the result is a tank full of vibrant and enchanting fish swimming gracefully with their flowing mackerel-like tails.
