Aquarium fishes: Goldfishes

The oranda, known in Japanese as 和蘭獅子頭, is a popular ornamental goldfish species (carassius gibelio forma auratus) commonly kept in home aquariums. Distinct from veiltail varieties, the oranda features fleshy growths on its head and gill covers, most notably its “hood,” or ‘wen.’ This hood typically begins to develop around three to four months of age but reaches full maturity only after one to two years. While the hood can be considered fully developed by about 2 to 2.5 years, careful attention to water quality and diet can enhance its growth and overall health.

The veiltail goldfish is a popular ornamental breed, well-known for its striking elongated fins and a unique, fluffy tail that is notably longer than those of other goldfish varieties. This fish is an excellent choice for beginner aquarists due to its hardiness, although it does come with certain care considerations.

Veiltail goldfish are relatively undemanding; however, they require a suitable environment to thrive. One important aspect to keep in mind is their tendency to dig in the substrate, which can disturb the tank setup. Additionally, these fish have a hearty appetite and often overeat, which can lead to health issues. It’s crucial to monitor their feeding and provide a balanced diet to prevent overeating.

Moreover, veiltail goldfish prefer cooler water temperatures, making them ideal for unheated aquariums or outdoor ponds in moderate climates. By understanding these essential care tips, beginners can enjoy a thriving veiltail goldfish in their aquarium.
