The Sugarloaf Goldfish is a highly distinctive goldfish variety. With its round body shape resembling an ingot and its charming appearance, it has a special place among goldfish enthusiasts. Its unique appearance and graceful swimming posture attract the attention of numerous ornamental fish lovers around the world.
Origin and Development
The Sugarloaf Goldfish originated in China and is a Wenzho ng goldfish variety developed through long – term artificial breeding. Breeders selected and cultivated traditional goldfish varieties, continuously enhancing the characteristics of its round body and plump head, gradually forming the current Sugarloaf Goldfish. In recent years, with the global spread of goldfish culture, the Sugarloaf Goldfish has also gone global. Due to its unique ornamental value, it has received increasing attention in the international goldfish market.
Morphological Characteristics
The most remarkable feature of the Sugarloaf Goldfish is its unique body shape. The body is short and round, with a prominently raised back, resembling ancient Chinese gold ingots, which is how it got its name. The length of an adult Sugarloaf Goldfish is generally between 8 – 15 centimeters. The growths on its head are well – developed. However, compared with the Thai Lionhead Goldfish, the growths of the Sugarloaf Goldfish are usually more compact and round, without the exaggerated extension to the cheeks like those of the Thai Lionhead Goldfish. Its tail fins are wide, mostly four – lobed, and when spread out, they are relatively flat. When swimming, they sway like a skirt, adding a touch of elegance. In terms of body color, the Sugarloaf Goldfish is quite diverse, with common colors including red, white, red – and – white, and multicolored. The scales shine with a soft luster under the light.
Living Habits
The Sugarloaf Goldfish is a poikilothermic animal. The suitable water temperature for its survival ranges from 10 – 32°C, and the optimal water temperature is 20 – 28°C, which is similar to that of the Thai Lionhead Goldfish. They have a gentle temperament and are suitable for mixed breeding with other equally gentle goldfish varieties. As omnivorous fish, Sugarloaf Goldfish are not picky about food. Both animal baits such as water fleas and bloodworms, as well as plant – based baits such as special goldfish pellet feeds and cooked vegetables, are on their menu. However, due to the relatively round body shape of the Sugarloaf Goldfish, its swimming speed is relatively slow. When mixed breeding, it is necessary to avoid keeping it with fish that are too aggressive in grabbing food, to prevent it from not getting enough food. In contrast, the Thai Lionhead Goldfish swims more actively and has a relatively stronger ability to grab food.
Breeding Key Points
When breeding Sugarloaf Goldfish, it is recommended to choose a relatively large and deep aquarium to provide sufficient space for their activities. Since the Sugarloaf Goldfish has a round body shape and a relatively high demand for dissolved oxygen, good aeration equipment and a filtration system are required. At the same time, change the water regularly (replace 1/3 – 1/4 of the water volume every week) to keep the water clean and stable. In terms of feeding, the principle of “feeding small amounts multiple times” should be followed to avoid obesity and water pollution caused by overfeeding. In addition, the growths on the head of the Sugarloaf Goldfish are prone to infection due to poor water quality. Special attention should be paid to water quality management during the breeding process to prevent diseases. In comparison, although the Thai Lionhead Goldfish also needs to pay attention to the care of the head growths, due to its different body shape and swimming habits, in the layout of the breeding space, some areas for swimming through can be appropriately set up.
