Le Japanese sailfish is a real star of the aquarium scene, with its elegant fins and bright colours. Native to China and Japan, this little aquatic jewel has fascinated hobbyists for over a thousand years. As an aquarium enthusiast, I'm going to guide you through the secrets of breeding and caring for this magnificent fish.
The origins and characteristics of Japanese sailfish
A history stretching back thousands of years
Le Japanese sailfish is the result of a meticulous selection process based on the common Asian carp. This species, scientifically known as Carassius auratus auratus, belongs to the Cyprinidae family. Its history goes back more than 1,000 years, making it one of the oldest ornamental fish in the world.
I was lucky enough to visit some traditional fish farms in Japan, and I can tell you that it's fascinating to see how these fish have evolved over the centuries. Japanese fish breeders really do have unique expertise!
A remarkable physique
What distinguishes Japanese sailfishis, of course, its magnificent fan-shaped tail. But that's not all! Here are its main physical characteristics:
- Short, stocky body, with a rounded shape
- Long fins, particularly the double caudal fin
- Adult size varies from 12 to 30 cm
- Wide range of colours: red, white, black, orange, calico, etc.
A peaceful, sociable character
Beyond its appearance, the Japanese sailfish is distinguished by its behaviour. It is a peaceful, lively fish that likes to live in groups. This sociability makes them an excellent choice for community aquariums. I've always been impressed by their curiosity and liveliness when swimming in schools.
Maintenance and care of Japanese sailfish
The ideal home
For your Japanese sailfish to flourish, you need to provide it with the right environment. Here are the main points to bear in mind:
| Parameter | Recommended value |
|---|---|
| Minimum volume | 50-100L for some specimens |
| Temperature | 15-30°C (18-24°C ideal) |
| pH | 7-8 |
| Hardness | 5-15°dGH |
Don't forget that a powerful filter is essential for maintaining good water quality. Regular water changes are also crucial. Personally, I recommend changing around 20% of water every week.
A balanced diet
The Japanese sailfish is omnivorous, which makes it easy to eat. You can offer it :
- Specific granules for goldfish
- Quality flakes
- Fresh or frozen food (bloodworms, artemia, etc.)
Be careful not to feed them too much! It's a classic mistake I made when I was starting out. One meal a day is more than enough, in small quantities.
Maintenance and health
These fish can live between 10 and 20 years with good care. However, they are sensitive to temperature variations and water quality. Here are a few tips on how to keep them in good health:
Monitor water parameters regularly. A weekly test is a good habit to get into. Provide a fine substrate, as they like to dig at the bottom. I opted for fine sand in my aquarium, and my fish love it!
If you live in a region with a temperate climate, you might consider keeping them in an outdoor pond. It's a great experience, but make sure the temperature doesn't drop too much in winter.
Remember that these fish prefer to live in groups. An aquarium with several specimens will be livelier and more natural. And if you want to diversify, you should know that there are related varieties such as the Oranda, the Ryukin or the Lionhead.
